      I'm delighted with how many people have been trying out Magnolia already! The Gitter channel (https://gitter.im/propensive/magnolia/ …) has been active all day. :)

      Take all the `A`s from any `Type[A]` and apply the given function to it. Turning it into a `Type [B]`

      No need to make it compile, of course. I'll do that. Just add a test to https://github.com/propensive/magnolia/blob/master/tests/src/main/scala/tests.scala …
