Actions of semigroup (SSet).

# Documentation

class Semigroup s => SSet s a where Source #

A lawful instance should satisfy:

g `act` h `act` a = g <> h `act` a

This is the same as to say that `act`

is a semigroup homomorphism from `s`

to
the monoid of endomorphisms of `a`

(i.e. maps from `a`

to `a`

).

Note that if `g`

is a

then `Group`

is simply a `MAct`

g`GSet`

, this
is because monoids and groups share the same morphisms (a monoid homomorphis
between groups necessarily preserves inverses).
