It's not a new problem -- there are plenty of warnings that can be generated 
during the source-level optimisation and suppressions don't work there right

Strange. I never saw anything like that. But if bootstrapping helped you, then 
I suppose it's fine.

Yes, I'm disappointed as well. Had hoped for some juicy pay-off, but no.

Thanks for testing it -- pushed to master, slightly simplified (somehow I 
completely missed the existence of `func-arity`)
