C++ - Python API

[Thomas Jollans]

On Wednesday 01 September 2010, it occurred to Markus Kraus to exclaim:
> So the feature overview:

First, the obligatory things you don't want to hear: Have you had a look at 
similar efforts? A while ago, Aahz posted something very similar on this very 
list. You should be able to find it in any of the archives without too much 
trouble.
The most prominent example of this is obviously Boost.Python.

How do you handle memory management ?

char*...
Unicode? Somewhere? wchar_t* maybe, or std::wstring? No? Also -- double? (I'm 
just being pedantic now, at least double should be trivial to add)

Which platforms did you test it on? Which compilers did you test? Are you sure 
your C++ is portable?

> -runs in multithreaded environments (requires python > 2.3)

How do you deal with the GIL?
How do you handle calling to Python from multiple C++ threads?

Again, have you tested other compilers?

Just publish a bitbucket or github repository ;-)
