I'm feeling like a bit of a troll here, but I can't help myself.

'in' is currently useless because scope is not defined properly, and const  
is too restrictive. Also, because of DIP25, it's now even more useless. It  
seems a pretty sure bet that it will either continue to be completely  
useless or be changed at some point anyways, so why not now? If it's only  
been around since 2.060, how bad could the code breakage really be?  
Replace All a few times and you're done. A compiler warning could be  
issued for the next few versions to notify users that the meaning of 'in'  
has changed, if needed.

So why not re-brand this awesomely concise and convenient keyword to be  
the "non-template auto ref"?
