Shed Skin Python-to-C++ Compiler 0.0.21, Help needed

[Mark Dufour]

Hi all,

I have just released version 0.0.22 of Shed Skin, an experimental
Python-to-C++ compiler. Among other things, it has the exciting new
feature of being able to generate (simple, for now) extension modules,
so it's much easier to compile parts of a program and use them (by
just importing them). Here's the complete changelog:

-support for generating simple extension modules (linux/windows; see README)
-dos text format fix (long overdue)
-improved detection of dynamic types (avoid hanging on them)
-improved overloading (__nonzero__, __int__, __abs__ etc.)
-add str(ing).{capitalize, capwords, swapcase, center, ato*)
-fix string.maketrans
-several other minor bug fixes

For more details about Shed Skin and a collection of 27 programs, at a
total of about 7,000 lines, that it can compile (resulting in an
average speedup of about 39 times over CPython and 11 times over Psyco
on my computer), please visit the homepage at:

I could really use some help in pushing Shed Skin forward. Please try
the latest release and send in bug reports, or join the project via
the homepage.


Thanks,
Mark Dufour.
