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. See
