zero-0.1.3: zero.cabal

name:                zero
version:             0.1.3
synopsis:            Semigroups with absorption
description:         'Monoid' is a 'Semigroup' glued with a neutral element
                     called 'mempty'. In the same idea, 'Zero' is a 'Semigroup'
                     glued with an absorbing element called 'zero'.
                     .
                     Keep in mind that 'Zero' requires 'Semigroup'. If you have
                     'Semigroup' defined to work with 'Monoid', you might end up
                     with no way to implement 'Zero'. That’s why the 'Semigroup'
                     instance for 'Maybe' is confusing, because it relies on
                     'Monoid', and cannot be used with 'Zero'. 'Success' is the
                     'Zero' equivalent of 'Maybe' + 'Monoid'.
