One really neat feature is that you can put a .pxd file next to your .py file and let it override the function signatures and classes. So you do not even need Py3 annotations, which have the obvious disadvantage of requiring Py3. That is not much of a disadvantage for code intended to be compiled.

... unless you have a reason for caring about a pure Python mode, which usually is because you want it to run in pure Python. :)

When Cython becomes part of the stdlib, say, in Py3.1 and/or 2.7, this means that those future Python versions that support annotations will (mostly) also support Cython compilation. Earlier CPython platforms and non-CPython interpreters are the problem here.

Support for nested defs and generators is much more critical.

Agreed. Given the current status of the implementation, that's only a question of time, not a technical issue.

Typo? Should 'typedef(cython.pint)' be 'cython.typedef(cython.pint)'? Also, the 'enhancement' page has separate misspelled 'seperate' twice.

Thanks for catching those. I also added a link to the Wiki.
