We have something very like this inside GHC, except we call it 'split'.
It's very useful for splitting up file paths into components.

For comparison, Perl calls it 'split'.  In Perl, 'chop' does something
different.  Python also has a 'split' function that does something
similar.

Does anyone object to calling it 'split'?
