AFAIK, the binary module was introduced in R14A. In fact, I upgraded to
R14A just so I could make use of the binary pattern matching in this module.
What I do with binary:split would take much more code with binary matching
(I think). Maybe you were thinking of erlang:split_binary/2?
Anyways, I digress. I don't want to hijack the original thread. I'll post
a new thread later today.
