So now I'm wondering how much tinkering's required to reverse engineer
the docs on the third argument to re:split/3 ;)
I'm always looking up function docs, for which args come when (they
tend to be different, wildly) and options. erlang.org/doc/man is a
very important resource and it'll answer a lot of questions for you.
Of course the shell is indispensable for playing around with the
functions - but life is much easier if you have an idea how to use
them in the first place.
