Hmm, connecting a slot doesn't happen very often, usually just once, so from 
this POV it's not a bottleneck.
OTOH the connecting usually happens on application startup and it's a "core" 
feature of Qt, so it should be as fast as possbile.

Using the normalized signature in the code wouldn't look exactly nice, many 
might consider it a bug when looking at the code.
Maybe some clever macros or templates could help ?
