It seems to me that in a policy-based design, the main class needs
to know if the policies are metafunctions or metafunction classes.
Now, I was under the impression, based on what Aleksey said a long
time ago, that these are basically interchangeable through a lambda-
based policy adaptor. But clearly, they are not if the policy client
has to know whether to look for types/functions in the policy, or the
nested apply<>. Any explanation?
