Ergonomic facade over the generated ladder binding.
A ladder is the answer to a node with more than one way to reach the network
and no single one that always works: rungs are tried in the order they were
added, cheapest first, and a message no rung accepts goes into a buffer
rather than being lost.
The delivery outcome is re-exported as a runtime Delivery object,
because the generated enum is types-only.
