[Python-ideas] Replacing the if __name__ == "__main__" idiom (was Re: making a module callable)

[Gregory Salvan]

my cent:
I think it's most often a bad practice (whereas it's convenient) to mix
"executable" and "importable" code.
Providing an easier way to do it, may encourage a bad practice.

I would prefer a solution which encourage separation of "executable" and
"importable" code.
