Well, if you have suggestions on how to improve emplace, then please create an 
enhancement request and/or a pull request. And with properly written custom 
allocators, all of the special casing should then be _in_ the allocator where 
you won't have to deal with it, making it so that you'd only really need 
emplace directly when you're doing something that none of the custom 
allocators will do (or you're writing your own custom allocator).
