This strikes me as in opposition to the Python-level policy of duck typing. Would it be more appropriate to, instead of asking if it's Python 3.3.0, ask if it's a Python that supports PYFEATUREFOOBAR? Or would that result in an unnecessary proliferation of flag macros? It would, hence I'm -1. I believe it is the motivation for the gcc assertion preprocessor feature, which never caught on.

Right, if someone wants to check for a specific feature rather than just figuring out once the minimum version of the stable ABI that they need, then they can write an autotools macro (or equivalent in other build systems).

Cheers, Nick.
