Hello,
I've recently run across an odd situation. I have a brand new install
of GHC-6.12.1 (just did a fresh install of OSX 10.6), and am
reinstalling some libraries. I've run into an unusual problem. I'm
not sure if this would be considered a cabal bug or not, but I don't
think it's a good sit

I'm writing a parser for a Haskell-style language, and when I need to use
the same symbol for infix, prefix and postfix operators, the combinator
"buildExpressionParser" seems not to work as intended. For example, in:
(1)x + y
(2)x +
(3)+ x
If I set the priority of the postfix version of "+" to b
