7>I rarely make a single prg with lots of functions and procedures. I therefore rarely need this feature and even if I used it, it would never be slow, because my prgs are tiny.
That is matter of approach :)
I have most of my classes in prg code,
and 95% of production code are code subclasses of those classes.
Form code are 'tiny' pieces, calling 'underworld' to perform some action.
So for me this feature is a 'must' :)
