Comment (by igloo):
Replying to [comment:8 NeilMitchell]:
> Surely OPTIONS_* where * is not GHC should be treated as a valid pragma
aimed at someone else?
I'd certainly want a warning for `OPTIONS_HGC`, `OPTIONS_FGX`, etc.
> I don't want users of Derive or Yhc being told that their pragma is
invalid.
They are told their pragma is "unrecognised", not "invalid".
> I also have a CATCH pragma that I've used in a few places. I realise
that GHC wants to give good error reporting, but it seems a shame that I
have to centrally register pragmas. Could there be a {-# KNOWN_PRAGMA
Catch #-} style pragma?
We could do that. We might have to jiggle things around a bit to make it
all work out.
