Description

  • We need to port tfae_have and tfae_finish. We have basic versions for mathlib parity via #2062.

  • The internals could be made more efficient (e.g. by finding strongly connected components).

  • We'd also like to add a block tactic version of tfae, i.e. tfae with .... using | and =>.
