Synopsis:            Supply applicative, monad, applicative transformer and
                     monad transformer.

Description:
    The @Supply@ monad represents a computation that consumes values from a
    provided supply.
    .
    This package comes with two separate implementations,
    @Control.Applicative.Supply@ and @Control.Monad.Trans.Supply@. The former
    provides an applicative and applicative transformer, the latter a monad and
    monad transformer.
    .
    The reason for providing two separate implementations is that the
    @Applicative@ instance of @Control.Monad.Trans.Supply.SupplyT@ incurs a
    @Monad@ constraint on the wrapped type, meaning it's not possible to
    (usefully) wrap a type that only has an @Applicative@ instance.
    .
    The implementation of @Control.Applicative.Supply.SupplyT@ has an
    @Applicative@ instance for wrapped types that are only @Applicative@, but
    this implementation cannot be made an instance of @Monad@, meaning it is
    less powerful than the version from @Control.Monad.Trans.Supply@.
    .
    In general, use @Control.Monad.Trans.Supply@ unless you're wrapping a type
    that has no @Monad@ instance, in which case you can fall back to
    @Control.Applicative.Supply@.
