What about __doc__, __name__ and __slots__, to mention just a few?
I believe that __import__() is the recommended way to import a module
known only at runtime. The docs also don't seem to agree with your
assertion that __import__ is not to be touched. On the contrary:
"The function is invoked by the import statement. It mainly exists so
that you can replace it with another function that has a compatible
Far from saying "Do Not Touch", the docs say "Please, go ahead and
replace __import__ if needed". If the OP wants "import x.y.z" to load
module z instead of x, it seems to me that is exactly the problem
__import__ is designed to allow him to do.

That may very well be true, but I don't know why you're dumping on me.
It wasn't my suggestion to change __import__. I merely said I could see
some advantages to it. I spent most of my post telling the OP why I
thought his arguments were wrong!
