Log Message:
-----------
Arrange for ValuesScan to keep per-sublist expression eval state in a
temporary context that can be reset when advancing to the next sublist.
This is faster and more thorough at recovering space than the previous
method; moreover it will do the right thing if something in the sublist
tries to register an expression context callback.
