Indeed, there is no current feature to execute in a particular
stack frame. In most cases this doesn't matter much in the case of
dynamic scoping; even in those cases where a later binding hides an
earlier one it's very frequent that both bindings have the exact same
value (typically an argument passed through a few levels of function
calls, with the same name at each stage).
With lexical scoping, this becomes more important.
Actually a good eval-in-stack-frame might even want to first undo the
corresponding let-bindings as well as save-excursions and friends, but
it would require more significant changes.
