I discovered just now that Coq 8.4 supports dependent subgoals, if a bit awkwardly.  In the following, solving the second goal instantiates an evar in the first goal:
Goal True.
  eapply (let x := _ in _).
  Grab Existential Variables.

Was this known?  Was this supported?  (I know that the ssreflect plugin gave limited support for dependent subgoals in 8.4...)
