Yes..
You need some sort of response class that has a .write method... this can be
a hacked up cStringIO or other.
Alternatively you can perform the same thing manually by passing in writer,
which instead of the template engine writing ``response.write("%s")`` it
could write whatever you want as a callable function.
So for example, say you defined your ``CustomResponse`` class as earlier in
the list...
context['response'] = CustomReponse()
exec(parse_template(...)) in context
print context['response'].body.getvalue()
SO yeah... in the end if we implemented your suggestion of overriding the
response class on import, then the render function would work as expected.
