Actually, I'm not going to try to convince anyone to make this a stable public API until after I've failed to convince you that maybe there ought to be a libpython.so on AIX. On AIX, the dynamic linking model is in some ways a lot like that of Windows, and it's really tough for a shared library to get ahold of symbols from an executable (witness the strange implementation of the title function of this email on AIX). If it didn't break something else, it might be a major simplification to move the bulk of Python into a shared library on this platform, just as it is on Windows... especially for poor unsuspecting souls (like me) who try to use the Python 'C' API from a shared library (not an extension module). Without some major hackery to patch up those symbols, it unceremoniously dumps core when you try to call Python functions. > > On a related note, I wonder about all of the _[A-Z] names in > > Python.
