synopsis:      Anything that associates
description:
    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.

flag hashable
  description:
    You can disable the use of the `hashable` package using `-f-hashable`.
    .
    Disabling this is an unsupported configuration, but it may be useful for accelerating builds in sandboxes for expert users.
    .
    If disabled we will not supply instances of `Hashable`
    .
    Note: `-f-hashable` implies `-f-unordered-containers`, as we are necessarily not able to supply those instances as well.

  manual: True

flag bytestring
  description:
    You can disable the use of the `bytestring` package using `-f-bytestring`.
