Maybe, we can just decide that all reasonable compilers support NRVO, and
stop worring about returning vectors/list by value? At least, when I write
function which returns a vector, I start it with

  vector<...> result;

so NRVO would surely work. The primary reason for 'result' is that I like
all functions to have a single return, but as a side effect it make NRVO
always working.
