At least not better. However I suppose that plain code is easier to 
optimize than an outcome of generic instantiation. Maybe that is the 
reason why GNAT inlines generics.

No, I don't use functional languages. Generics might be natural for 
non-computational languages (if you have no side-effects, there is 
nothing to compute, right? (:-))
