And the answer is: nowhere for now :)

Because I can't code it properly without relying on internal details of MPL.
Note I registered templates up to vector10<>. But only Aleksey knows how
many of them should be registered, and under which circumstances. This is
related to BOOST_MPL_LIMIT_VECTOR size, and which headers are actually
included, such as vector30.hpp or vector40.hpp...

So this is just an _example_ of what to do on the typeof part. What to do
on MPL part -- I can only guess. That's why I think such registrations
should be ultimately maintained by the library authors.
