   I read part A and part B. I like part A, since there is not only
grok.template(), but I think grok.viewletmanager() which have the same
problem, and it's quite annoying as well. And I agree on the expected
behavior of CLASS_OR_MODULE, even if it's considered as 'complex'.

  I would say 1) b), since it's better to keep things simple.
