But you have to understand a few things to understand why this works.
You have to know that __name__ is the name of the module, and that if
you want to find out the name of the main module, you need to look at
sys.main. With the idiom::
all you need to know is that the main module has __main__ set to true.

Could you elaborate? Do you think it would be hard to introduce
another module-level attribute (like we already do for __name__)? Or
do you think that the code would be hard to maintain? Or something
I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a
tiny blip on the distant coast of sanity.
