I don't see an indication that anybody but the creator of Psyco does understand the code base. *g* Guido has stated his opinion about optimizations more than once. My own opinion as core developer (which is quite similar to Guido's opinion) is: We are happy and glad for every improvement regarding speed, memory usage or features if and only if: * The implementation must be clean, well designed, well documented well written and platform independent / supported on all platforms. Python runs on machines from mobile phones to large main frames. * The improvement must NOT hinder or slow down future development at all cost. If it's so complicated that it might slow down future development than it's a no go. It's more important to us to have a clean and understandable code base than to add hundreds of small improvements which makes debugging a nightmare. * You are willing to support and fix the improvement for X years where X is between 4 and INF years. * The modification must not slow down Python for common uses like a single threaded, single CPU bound program or small script. This rules out all existing attempts to remove the GIL from Python since they have slowed down Python to 50% or less. However Guido said a few months ago that he would endorse a SMP branch of Python aimed to multi core and multi threaded apps. * The code and all its dependencies must be compatible with Python license. * The code must be written following the C89 standards. By the way core development is open for everybody. Any patch is appreciated, starting from fixing a typo in the docs over bug reports, bug fixes to new features.
