I think it would be a tad more convincing if there was a way to pass
arguments too (even if just a list of strings). At the very least extra arguments should end up in sys.argv[1:].
Could python -m 'module:thunk' have exactly the same behavior with respect to arguments as `python3.8 -m module` does today?
``` $ cat bar.py import pprint, sys
def thunk(): pprint.pprint(sys.argv)
if __name__ == "__main__": thunk()
$ python3.8 -m bar -- -1 --two --three=3 ['/Users/michael/bar.py', '--', '-1', '--two', '--three=3'] ```
So then with the same bar.py, `python -m bar:thunk -- -2 --three --four=4` would print `['/Users/michael/bar.py', '--', '-1', '--two', '--three=3']`. I like this better than my previous suggestion to shorthand python -c.
Actually it should print the same except for sys.argv[0]. (We could argue about what sys.argv[0] should be.)
Then again, presumably the function must be specially crafted for this usage. Why can't you just specially craft a module's main()?
I'm not sure I know what you mean by "specially crafted", other than the function only needs not require any formal parameters. It doesn't need to be special-er than that. It can handle args via sys.argv, as you suggested. Most of the `main` functions I write today are just like that.
Okay, so this is just a way to choose an alternative main() function. I'm kind of meh at this point, I'll leave it to the usual crowd. :-) -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-c...>
