"from PyQt4 import Qt" imports every module if I'm not mistaken.
Wanting a sane way of referencing Qt's symbols is not the same as
wanting every symbol from every module to be imported.

Surely losing that one character is great if it's unnecessary. The
QtRuby guys seem to use exactly the same naming system that I propose
and it works fine for them and looks much better.

The main Qt library does not for its separate modules, which is what
I'm talking about. I'm not proposing getting rid of every namespace

Could you please elaborate as to why?
