Right. That's exactly why we've not done something like that. With 100+
modules in the Gtk package it's totally infeasible to do qualified
imports of them all.

If we get a proper way to export a non-flat namespace then Gtk2Hs will
certainly switch to using it. Using 'buttonBlah' is horrible but there
is currently nothing better.

There have been a few suggestions along these lines. Check the archives.
I'm not sure what is proposed for haskell', probably nothing since
nothing is currently implemented and we're only supposed to be
standardising existing practise.
