 as per https://ghc.haskell.org/trac/ghc/ticket/11195#comment:9 and the ghc
 8.0rc release notes,`-fmax-pmcheck-iterations` is now a flag! its not
 listed as a documented flag, aside from mention in the release notes
 (though a search for pattern or matching will have a hard time turning it
 up)

 is this deliberate or not? (nb: not that i've used it, but making note of
 that subtlety)
