arrow notation example can't be parsed

This expression can't be parsed:

bug f g = proc x -> f >>> g -< x

Brackets are needed around f>>>g to get it through the 
parser. Can't see any justification for this -- the 
documentation suggests any expression is allowed 
before -<, and indeed, >>> cannot be confused with a 
command operator because f is not a command.

Are you parsing -< as an operator with a precedence 
greater than >>>? Hard to see otherwise why this 
doesn't parse.
