# about whether or not `gmp` is used; this comment is just here to explain
# why the `gmp` dependency exists despite what the release page says.)
#
# For GHC >= 8.10.6, `gmp` was switched out for `integer-simple`
# (https://gitlab.haskell.org/ghc/ghc/-/commit/8306501020cd66f683ad9c215fa8e16c2d62357d),
