Continuations fail to revert all registers to the correct state

Description

When the attached code is run, it outputs "foo\nfoo\n". The second foo should, in my opinion not be there. When the continuation to backtrack in choose() is created, val has not yet been assigned a value, and since choose() doesn't return a value on the backtrack (an intentional bug, to expose this behaviour) it should be in the same uninitialised state it was when the continuation was created.
