Say we have ~1400 primitives this should translate into ~4.5 min > of build time for something that in the average case is largely unused. But do we really need 1400 different trampolines? Can't these all just be copies of a small number of "base" trampolines (presumably one needs a different trampoline for every number of arguments, but that's about it, right)? Stefan
