I'm not talking about such cases. I meant only RAISE statement,
because its usage denotes an exceptional program's behaviour that
is generally rare. And BTW, "case" example you've mentioned if you
apply strategy I've proposed will be slow only in loops.

Anyways, I think there is some research needed in this field -
optimising stackframes insertion will obviously give a general speedup.

But anyways, "raise" optimisation could be very useful. (in fact, I'm
forced to use doraise; procs now, but this is VERY unpleasant).
