When looking over the Loot compiler, I noticed that the runtime environment and compile.rkt all look like they can and should handle returning a procedure, e.g. (lambda (x) x) -> "#", but the unload-bits-asm.rkt does not like this -- I am getting "; match: no matching clause for ...". I feel like it is as simple as matching (? proc-bits? i) but I thought this was worth mentioning.
