Hello Terrence,
Thanks for the nice patch... adding "use" clauses proves indeed difficult with 
current puic and your solution looks fair.
It might be a tad confusing/unintuitive to have use statements in an "include" 
section, but still it looks like the best Perl analogy we can have.

Anyway, I'll test it a bit usability-wide and eventually commit it.

Cheers,
Germain

(that's really too bad this whole Qt Designer support still looks like a big 
fat hack... I wonder how hard it would be to implement full PerlQt support 
directly inside the designer. 
I didn't look close at the code yet but it looks like it's quite ready for 
other languages support... 
The most tricky part would obviously be to have the changes included back by 
Trolltech.)
