trait Tell[F[_], -L] extends Serializable

Tell[F, L] is the ability to "log" values L inside a context F[_], as an effect.

Tell has no external laws.

Tell has one internal law:

def writerIsTellAndMap(a: A, l: L) = {
  (tell(l) as a) <-> writer(a, l)
}

def tupleIsWriterFlipped(a: A, l: L) = {
  writer(a, l) <-> tuple((l, a))
}
