Is it statically typed? Do you have ADT support and/or an object system? GC / refcounting or manual memory management?

How are you implementing bind() and currying in a compiler? I'm targeting x86 and my approach is to make little stubs on the heap that push a single parameter, then i can throw them around as ordinary function pointers (lambda lifting every single parameter rather than looking up things through environment pointers at runtime). The problem with this is that i end up with a huge amount of small fixed-size objects on the heap, which is a little less than ideal but at least i can write a special allocator for that case.

EDIT: Upon a little background reading (and your illuminating february blog post on concatenative languages) i realise you're probably referring to Kitten, in which case i'm not sure any of my current questions are remotely applicable.
