right now, the Typed-API does all the mapping in one scala.Function1. But if you do:

val mid = a.map(f1)
val end1 = mid.map(f2)
val end2 = mid.map(f3)
``
Then end1 will compute `f1 andThen f2` and end2 with compute `f1 andThen f3`. In some cases this will be much worse than only doing f1 once.

We should at least allow explictly forcing the intermediate node, and it would be nice if it automatically happened.
