However, there may be people relying on current behaviour, and the
motto of x.y.z releases is "nothing breaks".
Also, to get it into 2.2.1 you have to convince the person putting
patches into the 22-maint tree, and that currently seems to be me, and
I'm not checking this one in.

It can be useful too; I have actually done
>>> f = open("blabla
and then used tab-completion to finish it off.

I should have mentioned this before:

Huh? Who said anything about 2.1.x? (If it was me, that was a typo
:). It'll go into *2.3*.

Well, that 2.1.x != 2.3, perhaps...
incidentally, asking why things are "left out of the language" is
a good sign that the asker is fairly clueless.
