Replacing reservedOp above with:
reservedOpNf :: String -> CharParser st ()
reservedOpNf name = try (reservedOp name >> notFollowedBy (oneOf "|&="))
fixed the problem.
Hi Erik,
There is an easy, better solution, modifying the lexer:
> lexer = makeTokenParser $ emptyDef
> { L.reservedOpNames = words "&& || & | ^" }
> reservedOp = P.reservedOp lexer
> identifier = P.identifier lexer
> ...
I'd try to avoid 'try', if possible.
