It will not be source-compatible because the class name will be different. 
That's not what I was advocating.

I was advocating having a similar API (what Matthias called "static 
polymorphism" in his article on QQ13). That is, having an 
	int indexIn(const QString &string) const;

method. It brings familiarity: people who used this method in QRegExp will 
know what to expect.
