[Haskell-cafe] Re: problem with implicit parameter

Hi there,

I've written the following program

putchr = putChar ?d

main = do { c <- getChar ; putchr with ?d = c}

I think you're supposed to use a let binding, like this: putchr :: (?d::Char) => IO () putchr = putChar ?d main = do c <- getChar let ?d = c putchr Best, -- Grzegorz
