I'd like a library which simplifies the implementation of expression templates.
However, I'd like it to be more general than you have outlined. For instance I
might not want a + -b to be computed as a - b, but I'd like to have this as an
option, and not just for this particular sequence of operations. Also, I don't
think it needs to be so heavily macro-based.
