Except that it's not very reasonable to discuss Boost's requirements
at this point. About 10 different persons will immediately jump out,
suggesting that we "evaluate" alternative solution 1...N. About 10
other people will make various random complains about Python, and the
discussion will likely take a month, without any outcome.
Having concrete code will frame the discussion in a completely
different way, like "we have this Python port, that is 2x less code,
and is 10x faster and takes 10x less memory, where do we go from here".
There'll be no place for guesses and speculations.

Cmake download is 2.5M, and Python is 10M. This is already
not very significant difference, it "just" 4 times. And if
we're going to use Python->EXE solution on Windows, I
suspect there will be no difference at all.
