What's the feeling on having a FIXME pragma so that I can attach warnings to unfinished things?
{-# FIXME foo "Reasons here." #-}
I would use the WARNING pragma but that doesn't work within a module and only triggers on use. Compiler errors are the one thing I and everyone else pays attention to, it would be very handy to have more control over things GHC reports to the developer to aid development.
do you want GHC to print a warning here, or an error, or either depending on your flags? I thought there was a GHC trac ticket that asked for a more general WARNING where you could specify the type of warning, and the warnings could be ignored/displayed/made errors per group; then FIXME would just be one such type. Unfortunately, I cannot find it – maybe it was just a discussion elsewhere. I believe people wanted to use it to warn about partial functions.... ah, that made me find it.
