@jalf: If you were to apply it to operator+, you could achieve O(n) and zero redundant allocations for repeated allocations, something which is still faster than rvalue references. In addition, you could optimize for example COW implementations by copying on write, not just "on index into non-const". There are other applications too where both performance and semantics can be improved with expression templates.

| Jan 25, 2012 at 20:05 | comment | added | DeadMG | @ChrisLively: If I were to submit a proposal suggesting such a change, then it would absolutely be a problem that I didn't know why it wasn't done the first time around, and it is absolutely programming relevant and the answer is very specific. | |
