Or a simple statement in the language definition that pairs can be
optimized away in the right situation, even if there are side
effects...? For example, a user defined new/delete that does a printf
could be considered ok, and that the compiler can get rid of pairs
output lines.
Making this a local decision would be a good language direction for C++.
