Please simplify this limit arg, removing the maybe-drop-empty-strings behaviour. Either positive limit or #f for all matches. It is trivial for the caller to remove the empty strings if desired, and simplifies the docs for regexp-split. Matching perl semantics is not necessarily desirable. The discussion following the previous thread (started by Nala) is quite useful. Semantics of many other implementations were examined and a good summary later included. (Which does remind me to get back to that TODO list…) Regards
