There's one change I'd like to see: the constructors should take rvalue references ;-)
But that would prevent lvalue references from ever being used.
I was kidding, of course, since we don't have rvalue references yet; but under the current proposal, the correct way to write forwarding functions would be to have all the functions parameters declared as rvalue references. (See http://tinyurl.com/62smc.)
However, since we can't explicitly specify the template parameters for a templated constructor, could reference arguments (of either type) ever be used?
Forwarding constructors which take arguments by reference should generally use const references. (See #2 of http://tinyurl.com/6enrw.) I wouldn't want to suggest that you switch to const references at this point, because I can't say it wouldn't break some existing code. (Someone else can probably say.) Jonathan
