synopsis: A partial binary associative operator
category: Algebra

description:
  A partial semigroup is like a semigroup, but the operator
  is partial. We represent this in Haskell as a total function
  @(<>?) :: a -> a -> Maybe a@.
  .
  The
  <https://hackage.haskell.org/package/partial-semigroup-hedgehog partial-semigroup-hedgehog>
  companion package provides support for checking the partial
  semigroup associativity axiom using the
  <https://hackage.haskell.org/package/hedgehog hedgehog>
  package.
