Cython vs. V Programming Language vs. XSharp (X#) vs. python-sql Comparison Chart

Cython is an optimizing static compiler for both the Python programming language and the extended Cython programming language (based on Pyrex). It makes writing C extensions for Python as easy as Python itself. Cython gives you the combined power of Python and C to let you write Python code that calls back and forth from and to C or C++ code natively at any point. Easily tune readable Python code into plain C performance by adding static type declarations, also in Python syntax. Use combined source code level debugging to find bugs in your Python, Cython, and C code. Interact efficiently with large data sets, e.g. using multi-dimensional NumPy arrays. Quickly build your applications within the large, mature, and widely used CPython ecosystem. The Cython language is a superset of the Python language that additionally supports calling C functions and declaring C types on variables and class attributes.

X# is an open-source development language for .NET, based on the xBase language. It comes in different flavors, such as Core, Visual Objects, Vulcan.NET, xBase++, Harbour, Foxpro, and more. X# has been built on top of Roslyn, the open-source architecture behind the current Microsoft C# and Microsoft Visual Basic compilers. We have added a new options page (tools/options/text editor/X#) where you can control which suggestions the editor will suggest in the "general" code completion list. Code completion after a colon or dot will show namespaces, types, members, etc. And code completion after AS or IS will show types and namespaces. Several preprocessor fixes to make the preprocessor more compatible with FoxPro and Xbase++. We have also added the #if and #stdout commands. We added several smaller fixes in the RDD system to improve the compatibility with Visual Objects, XBase++ and FoxPro.
