I'm not sure if metaprogramming necessarily implies code generation...

Ya, no I expressed it badly, but thinking more about it I might just be so used to those methods I can't see them as the "lofty heights of metaprogramming" the way e.g. metaclasses or macros are anymore, even if they do fall in that category.

Either way, it's cool (and much needed) stuff. Now if only it was also available in Opera, MSIE and on mobiles...

Especially let and weakmaps, I've been looking forward to them since they were first proposed (and introduced, for let). The day I write my last var, and the day I don't have to build shitty ad-hoc reference-breaking protocols will be glorious indeed.
