Default argument binding allows you to bind to an outer object rather 
than a name, but it doesn't help if you want to update the object:

 >>> def inc(jj):
...     def dummy(jj = jj):
...             jj = jj + 1
...             return jj
...     return dummy
...
 >>> h = inc(33)
 >>> print h()
34
 >>> print h()
34
 >>> print h()
34
 >>> print h()
34
