Which implementation are you using? IIRC, GHC didn't have it in Control.Monad before the 6.8 branch.

It's not in the Prelude but it is in Control.Monad in base version 3 and later. You're probably using an older GHC which has base version 2.x.

Thanks for the quick responses. Looks like I need to install a version later than 6.8.

GHC 6.8 comes with base-3 so has (>=>) in Control.Monad. Duncan
