This is a source-incompatible change (and the bool* ok = 0 is optional). You 
cannot add such an API in Qt 5. You'd need to chose a different name.

While I agree that the existing API is not nice, coming up with new names 
won't be much nicer. In Qt 6, I we can just use std::optional and similar. In 
Qt 5, personally, I'd say lets stick with what we have and not try to reinvent 
yet another part of the STL.

But that's just me.
