two monoids as one, in holy haskimony

Official package sites : https://github.com/chessai/semirings ·

Haskellers are usually familiar with monoids and semigroups. A monoid has an appending operation `<>` (or `mappend`), and an identity element, `mempty`. A semigroup has an appending `<>` operation, but does not require a `mempty` element. A Semiring has two appending operations, `plus` and `times`, and two respective identity elements, `zero` and `one`. More formally, a Semiring R is a set equipped with two binary relations `+` and `*`, such that: (R,+) is a commutative monoid with identity element 0, (R,*) is a monoid with identity element 1, (*) left and right distributes over addition, and multiplication by '0' annihilates R.

General

containers
Enable the use of the `containers` package. Disabling this may be useful for accelerating builds in sandboxes for expert users.
doc
Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
hashable
Enisable the use of the `hashable` package. Disabling this may be useful for accelerating builds in sandboxes for expert users. Note: `-hashable` implies `-unordered-containers`, as we are necessarily not able to supply those instances as well.
hscolour
Include coloured haskell sources to generated documentation (dev-haskell/hscolour)
profile
Add support for software performance analysis (will likely vary from ebuild to ebuild)
unordered-containers
Enable the use of the `unordered-containers` package. Disabling this may be useful for accelerating builds in sandboxes for expert users.
