in declaring fixity for an operator (\\) to get it to compile using ghc
6.10.4, I needed to use the following code
infixl 9 \\\
(\\) a b = etc ...
where I assume the first \ escapes the second \, using infixl 9 \\ generates
a syntax error
infixl 9 \\ used to compile no problems with ghc 6.8.2
what is going on here ? why do I now need to add an additional \ ?, where is
this change documented ?, is this a bug?
