Details
It may be reasonable to support a "drop { ... }" block in a frame as well as an obj. This would just get stuck into the implicit frame-exit path, to be run on failure / unwinding.
Pleasingly, since frames are already acyclic (being stacked) there's no need to restrict this to "only operating on immutables" the way there is in objs.

Hmm. This is actually not all that likely to be useful. The best entry typestate we could assume would be nothing-initialized, which is pretty much pointless for running code. Best to make do with RAII / obj dtors. Closing.
