Cyclone attempts to avoid some of the common pitfalls of the C programming language, while still maintaining the look and performance of C. To this end, Cyclone places the following restrictions upon programs:
Although Cyclone looks, in general, much like C, it should be thought of as a C dialects.

 C programming language at AllExperts
The C programming language (often, just "C") is a general-purpose, procedural, imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system.
By 1973, the C language had become powerful enough that most of the Unix kernel, originally written in PDP-11/20 assembly language, was rewritten in C. This was one of the first operating system kernels implemented in a language other than assembly.
Without such precautions, most programs may compile only on a certain platform or with a particular compiler, due, for example, to the use of non-standard libraries, such as GUI libraries, or to the reliance on compiler- or platform-specific attributes such as the exact size of certain data types and byte endianness.

Cyclone is a programming language based on C that is safe, meaning that it rules out programs that have buffer overflows, dangling pointers, format string attacks, and so on.
The goal of Cyclone is to give programmers the same low-level control and performance of C without sacrificing safety, and to make it easy to port or interface with legacy C code.
Cyclone is a joint project of ATandT Labs Research, Harvard, the University of Maryland, and the University of Washington.

 Cyclone
Cyclone is a "safe" version of C, and it uses static analysis to catch memory leaks.
Cyclone restricts the operations you can perform on regions so it can guarantee that you don't leak regions, and that you don't dereference data within a region after it has been freed.
Briefly, all the data in a Cyclone program is statically tagged with the region it belongs to (the tag is part of the type, so "an integer in region 1" is different than "an integer in region 2").

Since programming languages are artificial languages, they require a high degree of discipline to accurately specify which operations are desired.
Programming languages are not error tolerant; however, the burden of recognizing and using the special vocabulary is reduced by help messages generated by the programming language implementation.
There are a few languages which offer a high degree of freedom in allowing self-modification in which a program re-writes parts of itself to handle new cases.

The language also provides multiple facilities for defining data structures and enforcing the high-level abstractions found in modern programming languages.
Development of a practical source-level language will require new techniques in program analysis and type inference as well as careful consideration of syntax, language design and the organization of the run-time system in order to succeed.

The vital ingredients of the language are generics combined with a new approach to interfaces that includes a notion of self-types and union types.
When approaching hard programming problems, a language-enforced programming discipline is crucial, and a natural way to enforce it is through the type mechanism of functional languages.
In the examples I consider, programs interact with memory (giving rise to a calculus for destructive and non-destructive state update), with the control stack (calculus of exceptions), and with the syntactic representation of program contexts (calculus for run-time code generation and meta programming).

That is, it saves the state of the program from time to time, and uses these checkpoints to restore the state of the program at any time.
For example, since the early 1990's, when the C++ language was "re-versioned" (our term) to refine or add functionality in the compiler, programmers had to merely wait for the next version of the compiler (and for all compilers to comply with the new functionality for those having to write cross-platform applications).
If the Java language is re-versioned, not only does the Java compiler have to be upgraded, but the browsers or interpreters must also be upgraded to recognize the changes, which causes the programmer to have to wait for two of the critical functional pieces of the development process to be re-versioned instead of just one.
