That could lead to confusing situations. What should
the following do:

   def f():
     x = 42
     def g():
       def h():
       parent x
       x = 88

Should the assignment to x in h() create a name in
the scope of g() even though there's no assignment
in g() to establish that as its home scope? Should
it be an error?
