Actually there is, to some extent.  The execution user_ns can be a
dict-like object whose methods fire notifications onto listeners.  One
can't detect *all* changes (such as in-place modifications of deeply
nested mutable objects), but at least one can detect all variable
reads (__getitem__), new variables (__setitem__) and deletions
(__del__).

Just a side note...
