Monoid instances must satisfy scalaz.Semigroup.SemigroupLaw and 2 additional laws:
A semigroup in type F must satisfy two laws:
The binary operation to combine f1 and f2.
The binary operation to combine f1 and f2.
Implementations should not evaluate the by-name parameter f2 if result
can be determined by f1.
A monoidal applicative functor, that implements point and ap
with the operations zero and append respectively.
A monoidal applicative functor, that implements point and ap
with the operations zero and append respectively. Note that
the type parameter α in Applicative[λ[α => F]] is
discarded; it is a phantom type. As such, the functor cannot
support scalaz.Bind.
An scalaz.Apply, that implements ap with append.
An scalaz.Apply, that implements ap with append. Note
that the type parameter α in Apply[λ[α => F]] is
discarded; it is a phantom type. As such, the functor cannot
support scalaz.Bind.
