where is the join function ?

Question

Hi, I need the join function to add separators between the members of a list. I found this function in Data.List.Utils and Data.String.Utils. Unfortunately, those modules doesn't seem to be part of the standard platform.
As it's a quite standard function, I'm pretty sure it should be somewhere in the standard platform , maybe with an other name.

Any idea ?

Update

I have found the solution (but can't accept my answer, I have to wait for 2 days ???)

Answer 1

I found it (thanks Hoogle), it's called intercalate.
