Ok, what if we did not implement the binary operator's "+", "-", "*", and
"/" returning temporaries because of their inefficiency. Instead do just the
"+=", "-=", "*=", and "/="?
I would hate to see people write;
M4 = M1 + M2 + M3;
and listen to people complain about how slow C++ is.

Dang! It's going to be at least 2 years before this gets fixed. Any chance
of not supporting this set of users? Or is this really a boost::MSVCMatrix
class? and you recommend that everyone else use MT, or Pooma?
