Haven't followed all of this, but perhaps the simplest thing would be to define a new builtin function that returns True in the namespace of the main module and false everywhere else. It could be implemented by
pulling
'__name__' out of the caller's local namespace and comparing it to '__main__'. We could name this function __main__(), or perhaps less dramatic, is_main(). Then you could write
if is_main(): <do your main code>
Why not make it so that a module function named __main__, if it exists, gets executed when the module is run as a script?
I consider the fact that the semantics of __main__ execution are largely the same as those of any other module import to be a feature rather than a bug.
Yes, I'm quite happy with the current idiom myself. I was merely suggesting this in case many people start opposing the statu quo and start demanding another idiom :-) Regards Antoine.
