Hi,
I just checked in a little fix to allow running cython directly on .py files
(instead of requiring .pyx files). That gave me the idea of actually running
it on Cython itself, since people have been complaining from time to time that
the compiler is slow for certain sources.
There are a couple of things in the sources that do not compile, I attached a
log. Some of them should get fixed in the sources (like tuples in function
signatures, which go away in Py3), but some also show stuff that Cython does
not currently support, so there are things to implement.
It would be cool if we could get Cython into compiling itself. I think that's
a target worth going for, and I'm close to believing that it's not far away at
all.
