Simpler yeah, Several implementations of python ring a bell with that,
and I understand it's .pyc so it's a compiled file and ready for usage
as 'anyother'(I might be wrong on this, but sure it's the same as
converting the original py file straight back to c).

Every language has it's benefits, and it's devout worshippers, I love
python, I even give credit to Guido for inspiring my own language
deviation in C++. I like cross language diversity, so I do things
everywhere, and I see noone complaining all the time about any one
language, nor it's advantages to them, especially if they know it and
use it.
