I have been working on refactoring the API of mega_apply and friends. The purpose of that branch is to improve the performance of function calls. More specifically, in some cases (e.g. f_map) frame allocation, setup and deallocation could be avoided if the API permitted it. I will soon push a branch and ask for feedback on that. Now to the real questions:
apply_low.h contains a FIXME notice talking about new-style tail recursion. Could anyone elaborate what that is, which code to look at and how that works? arne
