Off the top of my head:
separate :: String -> [String]
separate  = 
separate s =
case break (',' ==) s of
(s,) -> [s]
(s,',':s') -> s : separate s'
_ -> error "how did we get here?"
There is at least one cunning rewriting with foldl, I think, but I
think this version is clearer.

We have lingered in the chambers of the sea
By sea-girls wreathed with seaweed red and brown
Till human voices wake us, and we drown.
