Branch: CURRENT, Version: 0.20nb6, Package name: hs-semigroups-0.20nb6, Maintainer: pho

In mathematics, a semigroup is an algebraic structure consisting of a set
together with an associative binary operation. A semigroup generalizes a
monoid in that there might not exist an identity element. It also
(originally) generalized a group (a monoid with all inverses) to a type
where every element did not have to have an inverse, thus the name
semigroup.

math/hs-semigroups: Fix build with GHC 9.8

This breaks build with the currently default GHC 9.6. Please bear with me
until I switch the default compiler.
