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...
