From: John Nagle on 8 Jul 2010 12:42 How is Unladen Swallow coming along? Looking at the site, code is being checked in and issues are being reported, but the last quarterly release was 2009 Q3. They missed their January 2010 release date for "2009 Q4", so they're now about 6 months behind their project plan. ("http://code.google.com/p/unladen-swallow/wiki/ProjectPlan") John Nagle

Ask this question in Unladen Swallow's google group. They don't bite! Luis

Shedskin is not an interpreter, it's just a way to compile implicitly statically typed python code to c++. So the project is more along the lines of Pyrex/Cython in its goals. I believe it's a great way to compile extension modules written in restricted python, although it could compile entire programs provided they don't rely on non supported libraries or modules. Only a few are supported to different degrees of completeness. At this moment, it seems that Pypy is the project holding more promises. Although I guess Guido has strong reasons to support Unladen Swallow. Lets see what happens... Luis |
