描述

Would there be a way to use pasteurize in setuptools similarly to use_2to3? i.e., only commit Py3 code, but have a setup.py that contains something like

setup(..., use_pasteurize=True)

and have the code be pasteurized when installing (and testing) on Py2.

The idea is that pasteurized code can look quite "ugly" (e.g. keyword only arguments), so I'd rather not keep it committed, but with a good test suite, I can still make sure that the pasteurized version always works on Py2.

研究方向
Investigate how use 2to3 is implemented in setuptools (e.g., the setup command or build clib). Then replicate a similar mechanism for pasteurize, ensuring it runs before building on Python 2. Update setup.py configuration and documentation.
