  NationMaster - Encyclopedia: Non empty
One reason is that we can easily make logical errors when we make hypotheses about the empty set, which is often nonintuitive and can be tricky to reason about correctly (see Empty set for further discussion of this).
On the other hand, there certainly are times when the empty set is a special case and really does need to be excluded from a hypothesis.
empty() does not see a string variable with nothing but spaces in it as "empty" per se.

 Optimizing Microsoft SQL Server Analysis Services: MDX Optimization Techniques: Optimizing NON EMPTY
Empty cells are a direct result of no data existing at the intersection of two or more dimension, and our MDX statements display them alongside the populated cells in the datasets rendered.
Empty cells have an impact on the evaluation of search conditions and value expression, but, perhaps more significantly from an information consumer perspective, they can adversely affect usability and compactness of the data returned from a query.
In short, NON EMPTY is used on a given axis to remove empty tuples prior to delivery of the result dataset.

 PHP: empty - Manual
Thus you have to override the magic-function __isset($var) to produce correct results for empty(..) in combination with a magic-overloaded property.
When the form is posted and empty() is used to check for empty values it will return true.
It would be nice though if empty() can 'correctly' parse and return a value for a function call within itself like other funcs.

Empty lines and whitespace-only lines are ignored, as are lines whose first non-whitespace character is a `#'.

When this parameter is set to no, the cleanup(8) daemon performs duplicate elimination on the rewritten recipient address only, and generates empty original recipient queue file records.

We also present an algorithm that computes the intersection of a volume with the slicing planes incrementally, that cancels the overhead of the intersection and texture coordinates computation introduced by the partitioning.
Rendering with empty space skipping is 2.8 times faster on average than without it.
To apply occlusion clipping, we propose the orthogonal opacity map that simplifies the transformation between the volume coordinates and the opacity map coordinates, which is intensively required by occlusion detection.

 Non-empty list - HaskellWiki
These errors occur because the true domain of the function is smaller than the function's type suggests.
Possibly at some future date (during the code review?) I'll be called to justify my hunch, to whatever degree of formality (informal argument, formal proof) required by the policies in effect.
If I fail at this justification, I'd better think what to do if the result of foo is really the empty list.

 Extensible Markup Language XML Tutorial | www.freejavaguide.com
An empty tag is a start tag with a slash in front of the closing angle bracket.
In practice, some XML processors may create a distinction by interpreting the textual value of as an empty string and that of and as null.
For example, if an element in a document is required to contain text that can be interpreted as being an integer numeric value, and it instead has the text "hello", is empty, or has other elements in its content, then the document is not valid.

 Binary Tree Structure   (Site not responding. Last check: )
When it is not empty, it contains a data object called the root element, and 2 distinct BiTree objects called the left subtree and the right subtree.
Suppose one of the subtrees is empty, then BiTree.remRoot() will change the state of this BiTree to the state of the other subtree.
For example, when the left subtree is empty, root removal of the parent tree will set the parent tree to its right subtree.

(It is common, both within this document and in observed spoken behavior, to refer to an empty string by an apparent definite reference, as in ``the null string'' even though no attempt is made to intern[2] null strings.
The phrase ``a null string'' is technically more correct, but is generally considered awkward by most Lisp programmers.

 A look at tethered and untethered galaxies
The calculations in the paper 'Solutions to the tethered galaxy problem in an expanding universe and the observation of receding blueshifted objects.' [1] lead to the counterintuitive result that a stationary or receding galaxy can be blueshifted, even in an empty universe.
However, this is due to the definition of distance (comoving distance), and here we demonstrate that 'radar distance' is a more reasonable definition for which the effect disappears in an empty universe.
I would argue that it is the other way round, and that it is the insistence on sticking to comoving coordinates which has lead to the attribution of physical causes for what is actually an effect of coordinate choice [7].

 IF...THEN abbreviated string comparisons fail - AutoIt Forums   (Site not responding. Last check: )
Now I'm not certain that AutoIt claims to be able to handle the abbreviated form for strings, but seeing that it handles empty strings correctly, and seeing that it does follow 3/4 of the generally accepted way of handing this construct, it's natural that many coders will use this, assuming that it works.
My point is that string tests, where empty is differentied from non empty, also works in all the other languages (in my experience) where the abbreviation for numerics work.
But even if that is the case, considering the 3/4 of the conditions I outlined work correctly (half the string tests included), it would be completely reasonable for a programmer to assume that testing of non empty strings works exactly as expected.

 The Python Tourist #4: None, empty, and nothing. | boodebr.org
To me, an empty object is still something as opposed to None which (I think) should be nothing, so this is confusing.
In my "C thinking" of the first example, I was assuming None meant "the absence of a value", so was surprised to find that an empty list was (apparently) the same as nothing.
I wish that empty lists didn't evaluate to False, but that's the way it is, so you just have to keep it in mind.
