[erlang-questions] [enhancement] string:split/2

[Robert Virding]

Can we end the language discussion? :-)

I suggest a function string:split/2 which splits the input string with the
separator and assumes that there is no separator and either end of the
string. So:

string:split("ab:de:fg", ":") ==> ["ab","de","fg"]
string:split(":ab:de:fg:", ":") ==> [[],"ab","de","fg",[]]

We call it split because it sounds better inspite of it being an unjoin.
This also matches what will be in the re module (if they get it right) and
what is in the old regexp module.

And I don't really care what its relationship to join is called. :-)
