Of all suggestions, this is probably the one having the least
performance impact and greater readability. It still doesn't solve the
code duplication issue (Samuel's does, but with a greater runtime
impact), though. :-(

Anyway, thanks all!

(I'm still looking forward to see this issue addressed at the QML
language level, though :-) )

Ciao,
