Re^2: Performance, Abstraction and HOP

[Anonymous Monk]

If Perl's function calls are slow, the right response is to try to fix the implementation, not to try to avoid function calls.

Or, if you can try the hybrid approach, and eat your cake as well as have it...

But, if you study programming languages, you discover that although there is a problem, through a small number of correctness-preserving transformations, this problem can be averted. And by being aware of the problem, you can better appreciate the merits of languages that manage to avoid it.

Maybe some links to overviews of things like defunctionalization, closure conversion, lambda lifting, and continuations passing style would also be helpful.
