Hola Ion,

Main problem with having something like an assocvector index
in Boost.MultiIndex is that indices are required to be
node-based, while much of the power of an assocvector comes
from its use of contiguous memory to achieve excellent
performance. So I doubt the merge would be satisfactory.
That said, I prompted some days ago about interest on a
random-access index for the library. If I finally write this,
it could be used as an implementation basis for an associative
random-access index. On another topic, "compatibility with
MultiIndex" amounts to rewriting the stuff: it is very difficult
that common code can be shared between a container and its
index counterpart.
