Without studying proposed Boost.LA's extension mechanism, is it possible
to use proxies for those vector/matrix types that only (natively)
provide a setter interface? That is, if that manages to keep the
Boost.LA interface convenient and/or improves efficiency for those types
which do provide reference-to-non-const access to components...
