semigroups: Anything that associates
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.

Automatic Flags
Name | Description | Default |
---|---|---|
bytestring-builder | Decides whether to use an older version of bytestring along with bytestring-builder or just a newer version of bytestring. This flag normally toggles automatically but you can use `-fbytestring-builder` or `-f-bytestring-builder` to explicitly change it. | Disabled |
Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
