This is an announcement of the beginning of development of a new Python-like language called PyCs (pronounced "pie-cees"). Like IronPython, PyCs will be Python on .Net but it will have more advanced features and probably have higher performance due to a Psyco-like implementation technique. See http://pycs.org. PyCs is a fusion of Python and C#. It is the first Python-like dynamic language with all the capabilities of C# including the capabilities of the research language C-Omega (http://research.microsoft.com/Comega/) including the X# language features (http://www.cl.cam.ac.uk/%7Egmb/Papers/vanilla-xml2003.html) that embed XML/SQL support directly in the language. At the same time PyCs keeps all the advantages of the Python language and the Python way. PyCs will not be source compatible with either C# or Python but code could be ported from either one easily. PyCs is being developed by Mark Hahn who developed Prothon and PyCs grew out of the initial efforts to port Prothon to .Net. For an explanation of why the Prothon port to .Net turned into a whole new language, see http://prothon.org/pycsnews.htm. PyCs is just now starting development and will be developed using the same XP-like language design process used to develop Prothon. This process will use the PyCs mailing list to design the language where Mark acts as moderator and implements the language in real-time as the ideas are worked out. He will be working on PyCs full-time and drive the development just as he did with Prothon. Please join the PyCs team. The only effort involved is particpating in a low-traffic, high-content, mailing list. You will be able to influence the design of the latest and greatest dynamic language. -- Mark Hahn, http://pycs.org
