Yes, certainly, what next ? multiplication ? (I hear that FORTRAN {8|9}x
got this one "wrong", i.e. a matrix multiplication is an element by 
element multiplication, not the 'lin. algebra' multiplication).

The point is that the semantics become non intuitive after a while.
Anyway, what's wrong with C++ ?
