> Metaprogramming doesn't need to have a performance impact.
Optimising away the performance impact of most of the metaprogramming features I mentioned there requires truly heroic optimisations, beyond what has ever been used for any other language.
Some of them are even worse - I'm not sure there any way to optimise away the non-local effects of Proc#binding, which allows you to access local variables not lexically referenced.
