Function flatMapT

flatMapT<W, M>(
    monoid: TypeClass.Monoid.Monoid<W>,
    monad: TypeClass.Monad.Monad<M>,
): <T, U>(
    fn: (t: T) => WriterT<W, M, U>,
) => (t: WriterT<W, M, T>) => WriterT<W, M, U>
Maps and flattens the Writer<W, M, T> with the computation over monoid W and monad M.
Type Parameters
- W
- M
Parameters
- monoid: TypeClass.Monoid.Monoid<W>
  The Monoid instance for W.
- monad: TypeClass.Monad.Monad<M>
  The Monad instance for M.
Returns <T, U>(
fn: (t: T) => WriterT<W, M, U>,
) => (t: WriterT<W, M, T>) => WriterT<W, M, U>
The computed one.
