I don't think there's any need for that. I also don't think this is an inappropriate question for this list or that the C code is particularly ugly for that matter, but there you go. Anyway, to answer your question, get the code from the link above and look at pp*.c. reverse(), taking your example, can be found by searching for pp_reverse in pp.c. If you are serious about understanding the code you'll also want to read pod/perlguts.pod.
