There is a cool-off period while C++14 is being finalized, in which no 
changes are accepted. That's ISO procedure. Once C++14 becomes an official 
standard, it'd become possible for N3640 to be discussed and, hopefully, 
accepted; it would then be up to individual compiler vendors to provide an 
implementation. There'd be no need to actually wait for C++17 for that, but 
officially, yes, C++17 will be the standard in which the changes will be 
published (if accepted).

The switch to a three-year cycle caught some of us off guard. I should have 
proposed shared_ptr<T[]> earlier, but I didn't, so that's where we stand 
now. Sorry. :-)
