This does not work within functions (as documented, I believe), where
locals() returns a dict that is a *copy* of the local namespace (which
is not a dict):
>>> def f():
...   a = 1
...   print a
...   locals()['a'] = 2
...   print a
...
>>> f()
1
1

It only works at module level because there locals() == globals(), so
it would be less possibly confusing to always use globals(), which
currently does always work.
