Hello Leandro,
If you say dynamic languages don't have metaprogramming capabilities,
you just don't have any idea of what a dynamic language really is.
If you say you can do metaprogramming at runtime you just don't have
any idea of what I want to do with metaprogramming. For example:
What you say next, is not metaprogramming per se, they are performance
issues (that you resolve using compile-time metaprogramming).
They are metaprogramming tasks. Dynamic languages can do some
metaprogramming tasks. They can't do those ones.
You are right, but if you *don't* need *speed*, you don't need all that
stuff, that's not metaprogramming to fix a "logic" problem, they are all
optimization tricks, if you don't need speed, you don't need optimization
tricks.
"you don't need speed" is a pretty glib statement. I think the reality
is that you don't care about constant factors in speed, even if they are
large (say 200 times slower is OK). But bubble-sort is probably still
not acceptable.
Metaprogramming can be used to reduce big-O complexity rather than just
constant-factor improvement. Lumping that in with "optimisation" is
highly misleading.
The kind of metaprogramming I'm talking about is, for example, generating
boring, repetitive boilerplate code.
