.... in cases. My point was mainly that just because Qt does something, 
doesn't mean it's good without making up your own mind. And jumps between
text segments _is_ slower than inlining a data accessor. The more often a
member is used, the more it hurts. And check e.g. QString::size() - no sane
developer would put that in an out of line function.

The same about malloc: the more a class is created, the more the private d
pointer hurts. And fortunately classes like KURL that we still create a lot is
not creating a Private - and that has to stay this way.
