Description
Currently while we do support Struct { field: N } as a const argument, we don't support things like Struct { field: N, ..N2 }. This is possibly something worth supporting. This will exacerbate #150621 and I'm not sure it's important enough to support this that we should do so before finding a way to share the logic.

Research direction
Start by investigating the existing support for Struct { field: N } as a const argument and read the related issue #150621. Determine whether struct expressions containing ..rest should be supported directly and how that interacts with the logic-sharing concern; the issue does not identify files, tests, or a settled completion criterion.
