It's a hassle.

Nope.  I've got readline or the emacs shell equivalent.

That and the fact that I almost always type:

   foo.keys()

and then get something useless and *then*, say "Doh!"
and then have to add the list call.

This is a case where I can give feedback based on actual
experience with a feature.  It's like you get user testing
for free. :)

I'd be interested to hear if other people who have experience working
with ZODB BTrees have been as annoyed as I've been.

Then again, I suspect that when you actually implement this
you or perhaps other will be as annoyed with this feature as
I am.
