edir() has a keyword argument: edir(x, dunders=False) suppresses the return 
of dunder names. But since the primary purpose of [e]dir is, in my opinion, 
to be used interactively, needing to type an extra 15 characters to hide 
dunders is too inconvenient.

Yes.

The primary use-case (at least *my* use-case, and hopefully others) is to 
have "from module import edir as dir" in their Python startup file. That 
means that when running interactively, they will get the enhanced version of 
dir, but when running a script or an application they'll just get the 
regular one.

(Ideally, the regular one will eventually gain the same superpowers as edir 
has, but that's a discussion for another day.)

Besides, apart from the inspect module, which probably shouldn't, who uses 
dir() programmatically?

(If you do, you'll be glad to hear that edir() behaves the same as regular 
dir() by default.)
