Hi all!
I've been playing around with the rules facility a bit. There is a boring
shortcoming when working with infix operators. It seems that the rule
parser doesn't like them at all. The following example gives syntax error:
{-# RULES
"plus/mult" forall p . p + p = 2 * p
#-}
whereas the following is allright:
{-# RULES
"plus/mult" forall p . (+) p p = (*) 2 p
#-}
It's not a big problem, but it's rather inconvenient and ugly. Is it easy
to fix?
Cheers,
/Josef
