[erlang-questions] list:join() for erlang?

Sorry that I made an omission.

I was referring to the variant of join which takes a separator. For example: lists:join("abc", "/"), which evaluates to "a/b/c".

Do you know if something like this exists in the distribution?

It does exist :


and the corresponding syntactic sugar :

1> [a,b,c] ++ [d,e,f].
