All good questions! I have nothing to add to that list.

Hello devs!
I am trying to implement some kind of local warnings suppresion and i need some help.
I want to use a pragma to mark functions so compiler won't throw warnings from them. I defined my pragma in lexer, parser and added type signature in HsBinds.hs. And i am stuck. I don't know what to do. What should i consider doing further?
I think it would be helpful to focus on further elaborating the specification before we move into the implementation. There are still a number of open questions about the design that the wiki page doesn't yet address. For instance, you should explicitly specify, * What are the identifiers that appear after the `SUPPRESS` token? * What exactly does the pragma apply to? For instance, if I have a case like, hello :: Int -> Int {-# SUPPRESS some-warning #-} helloAgain :: Type -> AnotherType hello = (+1) helloAgain = error "42" or even just hello = (+1) {-# SUPPRESS another-warning #-} helloAgain = error "oops" What do you expect to happen? The behavior of the pragma in both of these cases should be unambiguously stated in the specification. * An concrete use-case motivating the change (preferably with examples showing how the proposed syntax would address the motivation) I know this sounds repetitive, but the act of writing down a proposal will help you immensely when you do move on to implementing your ideas. Thanks for your persistence.
