Thanks for the clarifications. I now have a much better understanding
of what Cython is. But I'm not sold. For one, your attitude about
strict language compatibility worries me when it comes to the stdlib.
Not sure what you mean

Have you tried replacing selected stdlib modules with their
Cython-optimized equivalents in some of the NumPy/SciPy distros? (E.g.
what about Enthought's Python distros?) Depending on how well that
goes I might warm up to

[skipping the whole long discussion]
Cython is meant to compile Python code. A cython version would just be a
pure Python module, usable with all other implementations, but with type
annotations that make it compile to more optimal C code. Type annotations
can be provided in an external file

It appears that there has been little mention of Cython at the summit,
despite of the speed of CPython being a major topic, according to the notes.
I can see several areas where Cython could help in speeding

IMHO, taking modules that currently only have a C implementation due to
performance constraints and rewriting them in Cython is a much more
worthwhile thing to do than adding an alternative pure Python implementation
that other Python runtimes wouldn't use anyway. And at least

Hi Stefan,
I'm glad to see Cython picking up steam and trying to compete with
CPython, PyPy, and possibly others. It's true that few in the core
development group know much about Cython -- essentially my own
understanding is still that it's like Pyrex, which was a
mostly-Python-compatible syntax

Hi Stefan,

We do, although our main focus is much more on targeted manual optimisation
rather than whole applications.

Cython feels much less
mature than CPython; but the latter should only have dependencies that
themselves change even slower than CPython.
You might be slightly more amenable to Pyrex, then, which
changes at a much more conservative pace!
They appear superficially
The short summary is that the Parrot VM is a very good semantic fit for
Python (AFAICT, a better fit than it is for Perl 6, though I haven't
done the feature-by-feature comparison).
Thanks for the write-up. The point quoted above is especially useful,
since I vaguely remembered reading that
