What about introducing -fno-warn-pragma=XXX? People who use HLint will add -fno-warn-pragma=HLINT to their build configuration.
A warning flag is an interesting way to deal with the issue. On the other hand, it's not great from an ergonomic perspective; afterall, this would mean that all users of HLint (and any other tool requiring special pragmas) include this flag in their build configuration. A typical Haskell project already needs too much such boilerplate, in my opinion. I think it makes a lot of sense to have a standard way for third-parties to attach string-y information to Haskell source constructs. While it's not strictly speaking necessary to standardize the syntax, doing so minimizes the chance that tools overlap and hopefully reduces the language ecosystem learning curve. Cheers, - Ben
