If a typeclass constraint does not match - any of the declared modes for its class, the constraint is postponed, and - the proof search continues on other goals. Proof search does a fixed point - computation to try to solve them at a later stage of resolution. It does - not fail if there remain only stuck constraints at the end of resolution. - This makes typeclasses with declared modes more robust with respect to the - order of resolution. - (`#10858 `_, - fixes `#9058 _`, by Matthieu Sozeau). -- cgit v1.2.3
