Note that both Psyco and Cython make a lot less assumptions about Python code than Shed Skin does. Psyco has the advantage of just needing to jump in when it finds out that it can help, so it's the most broadly compatible of the three. But Cython also supports quite a large corpus of dynamic Python code by now. Shed Skin has a lot of restrictions, many of which are by design. It's not intended to compile dynamic code, and I think that's a good thing, because that's what makes it fast for the code that it supports. Getting the same speed in Cython requires a bit more explicit typing, simply because Cython does not assume these restrictions. I think that all three have their raison d'être, and it currently looks like all three are there to stay and to keep growing better. And I'm also happy to read that some optimisations jump from one to the other. ;) Stefan -- http://mail.python.org/mailman/listinfo/python-list
