language implementations using an Objective-C runtime for the object model.
This is used by SmalltalkKit, implementing Etoile's Pragmatic Smalltalk,
a Smalltalk JIT compiler which generates code binary-compatible with
Objective-C, allowing classes to be written in a mixture of Smalltalk
and Objective-C.

Distributed Objects. It simply exports a dictionary containing a set of named
objects for scripting with Objective-C or any languages based on the LanguageKit
such as Pragmatic Smalltalk.
This is used for example by the hit corners and gesture recognition tool to run
arbitrary commands in response to corner activations or mouse gestures, and by
ScriptServices which allows arbitrary shell or Smalltalk scripts to be invoked
on the current selection from any GNUstep or Etoile application.

some MSVC extensions. It also provides many useful analyses for warnings. It
uses libFIRM, which provides a SSA-based intermediate representation in form of
explicit dependency graphs, for optimization and code generation. Parsing is
done with a handwritten recursive descent parser. The AST representation is
straightforward, so it can be used for other purposes than code generation.
* fast recursive descent parser, parses C89 and C99
* handles most GCC extensions, f.e. __attribute__, inline assembler,
computed goto, statement expressions
* handles some MSVC extensions (like declspec)
* provides many useful warnings
* format string checker for char and wchar_t
* unreachable code analysis
* missing return statement check, which pinpoints exact location(s)
* write-only/-self variables detection
* missing and redundant forward declarations
* most warnings switches, which are available for GCC
* provides concise messages in case of error, for example when encountering
misspelled typenames
* compiler driver compatible with with GCC (-fxxx, -Wxxx, -M, ...)
* uses libFIRM for optimization and code generation (devel/libfirm)

as easy as Python itself. Cython is a source code translator based on
the well-known Pyrex, but supports more cutting edge functionality and
optimizations.
The Cython language is very close to the Python language (and most
Python code is also valid Cython code), but Cython additionally supports
calling C functions and declaring C types on variables and class
attributes. This allows the compiler to generate very efficient C code
from Cython code.
This makes Cython the ideal language for writing glue code for external
C libraries, and for fast C modules that speed up the execution of
Python code.
