Re: [Haskell-cafe] error on "--++ bla bla bla"

But in my program, I did not define "--++".

And that's what the error tells you, no? Defining operators (or not) doesn't change the syntax. Since the lexeme --++ is syntactially a valid operator, it will be parsed as such, regardless of whether it is defined or not. -k -- If I haven't seen further, it is by standing in the footprints of giants
