Here's one:

%lame example
Happy tells me: Foo.y:1: unrecognised directive: %lame
{- -} style comments seem to work, though.
Another minor point: Sometimes (right hand sides consisting entirely of
terminals?) Happy (without -g or -a) generates some superfluous
catch-all equations for the internal "reduction" functions (something
like "reduction _ _ = notHappyAtAll"). GHC correctly deduces that they
are completely overlapped by previous equations and issues a warning
(or two, or three...). While this doesn't really hurt, it makes the
"real" warnings much harder to find.
