OK by me.  Note that we agreed long ago that if nested scopes ever made it
in, we would need to supply a way to get a "namespace mapping" object so that
stuff like:

    print "The value of i is %(i)s and j %(j)s" % locals()

could be replaced by:

    print "The value of i is %(i)s and j %(j)s" % namespace_map_object()

Also agreed this need not be a dict; fine by me if it's immutable too.
