Description
It does work, but two issues:
[Error] Unbound value ??- maybe use a different message (e.g.Warning/Error: Unimplemented hole)refmtincorrectly formats it like this
Typed-holes are ridiculously useful for statically-typed programming (Agda, Idris) - would be great to shine some light on this feature - instead of/as well as gradually buildng types, we can gradually build terms :-)

Research direction
Start by reproducing the typed-hole behavior described in the issue, then inspect the error reporting path and refmt's formatting of (??). Done means providing a clearer unimplemented-hole diagnostic and ensuring refmt preserves the intended typed-hole syntax, with tests covering both behaviors.
