	PHP: Comparison Operators - Manual
		Comparison operators, as their name implies, allow you to compare two values.
		You may also be interested in viewing the type comparison tables, as they show examples of various type related comparisons.
		Note: Please note that the ternary operator is a statement, and that it doesn't evaluate to a variable, but to the result of a statement.

	Operator comparison
		Operator comparison =================== Operator comparison is the process of creating desirability preferences for competing operators.
		Soar's preference scheme supports relative comparisons, such as that operator O32 is better than operator o25, and it supports absolute preferences, such as that operator o25 is {worst} (see Section See preferences on page See preferences for more information on the semantics of preferences).
		The only available operators are to move A onto C or the table and to move C onto A. This final production creates worst preferences for operators that move blocks onto other blocks, when that is not their desired position.

	I know the answer (it's 42) : C#: Comparison operator overloading and spaceship operator
		I think the reason is that because the "operator ==" implementations are defined as requiring the variables to be known to be string at compile time.
		I think the reason why a spaceship operator is not included in c#, for your particular implementation at least, is that stepping through a list of truth tests until you find one that matches your case robs the program of performance.
		On the other hand, if each case of the comparison operator is overloaded individually, the only code called will be the code for the particular comp op that you specified, providing much cleaner execution.

	Expressions and Operators (Site not responding. Last check: )
		A comparison operator compares its operands and returns a logical value based on whether the comparison is true.
		The bitwise shift operators take two operands: the first is a quantity to be shifted, and the second specifies the number of bit positions by which the first operand is to be shifted.
		In addition to the comparison operators, which can be used on string values, the concatenation operator (+) concatenates two string values together, returning another string that is the union of the two operand strings.

		It would be nice to implement an operator like this one for everything in such a way that the set of all things in the language would be totally ordered, so that it could be used in the implementation of efficient hash tables, but we haven't done this.
		The methods which have been installed for this operator are fairly primitive, and in the end often amount to simply comparing hash codes.
		This operator may be used as a binary operator in an expression like

		The comparison operators are the ones which perform the comparisons when you are controling the flow of your program.
		This operator is used to check whether the value of the expression on the LHS of the operator is the same as the value on the RHS side of the operator.
		The logical operators are used when you need to combine more than one comparison operator in the same result or to modify the result, although they can also be used in other situations where you would use operators.

	Microsoft SQL Server - Lesson 5 SQL Expressions
		A comparison is a Boolean operation that produces a true or a false result, depending on the values on which the comparison is performed.
		The operators used are called logical operators because they are used to perform comparisons that produce a result of true or false (there is no middle result; in other words, something is not half true or half false or "Don't Know": either it is true or it is false).
		The comparison for a True or False value is mostly performed on Boolean fields, such a case is the SPHome (which specifies whether a student lives in a single parent home) field of the Students table of the HighSchool database.

		A comparison operator compares two strings and decides which is "smaller" and which is "larger" according to some criterion.
		Once a comparison operator is chosen, it must be applied to a portion of the input lines.
		Note that, as far as built-in comparison operators go, -c only has an effect in the "ascii" operator; all the others are always case-insensitive.

		Comparison operators are operators that compare data values against each other and produce true or false results.
		The comparison operators always compare data, and that comparison is either true or false because data either compares as expected or does not.
		The comparison operators are sometimes known as conditional operators because they test conditions that are either true or false.

		The method syntax for comparison is far more cumbersome than the operator syntax, and is poorly chosen as the required syntax for so common an operation.
		Code becomes locked into the choice of semantics that cause operator comparison to work, making it more difficult to maintain, because developers are faced with an unnecessary trade-off between ease of maintenance and ease of development.

		Calls and accesses to.NET and F# methods and properties (collectively known as members) involve a form of type-directed overload resolution, resolved based on left-to-right, outside-to-in analysis of a file, i.e., type information subsequent to the use of an overloaded member is not taken into account for its resolution.
		Operator overloading is resolved over the same scope as type inference, typically an entire file.
		Where operator overloading is not resolved the overloading typically defaults to work over 32-bit integers.
