Use explicit forall syntax to avoid warning #11

Closed hvr closed 10 years ago

hvr commented 10 years ago

This is currently just a warning in GHC HEAD, but ought to be fixed nevertheless:

Variable ‘m’ is implicitly quantified due to a context
Use explicit forall syntax instead.
This will become an error in GHC 7.12.
