File "setup.py", line 2232
self.add(Extension('_decimal',
include_dirs=include_dirs,
libraries=libraries,

undef_macros=undef_macros,
extra_compile_args=extra_compile_args,
sources=sources,
depends=depends))
I don't know about all the other examples, but in a setup.py that cries out for a more declarative approach: put all that in a dict, and call Extension('_decimal', **build_params).
In general, I think setup.py modules should be a lot for declarative anyway, but at a glance, that sure looks like you'd have the same set for multiple extensions.
I suspect that quite a few of the cases where folks are doing a lot of same-name kwargs passing could hve been better written with an intermediate dict. I'm not saying I don't do it myself, but honestly, it's a bit out of lazyness -- so I'm thinking that new syntax that encourages this style might be a bad idea.
