Tim> I'm still not sure I've got any use for __all__, though <wink>.
That may be true. I think the canonical case that is being defended against
is a module-level symbol in one module obscuring a builtin, e.g.:
# a.py
def list(s):
return s
# b.py
from a import *
...
l = list(('a','b','c'))
I suspect in the long-run there's a better way to accomplish this than
adding __all__ to most Python modules, perhaps pylint.
Which reminds me... I did write something once upon a time to catch symbols
that hide builtins, only at more than the module level:
