For my usage, it's always best for them to be perl types, but I can imagine 
that some people might have a use for actual Qt::Variant return values.  I 
think that you could either make it a runtime option, possibly set per 
function, or you could just make it a function and not do it automatically.

Yeah, I have this.  I didn't have any source to make a proper patch against 
and I forget to include it.
