Then hopefully we'll be able to get limited evaluation at compile time some time in the future, as they define what limited is. Hopefully.
Yes, this is very significant also. Remember, you can never back something out of a standard, only add to it, if you want to keep backward compatibility.Easier in the first instance (particularly with a large language like C++) to specify something in a restricted manner, and only relax restrictions if there is a real world need to do so.
The only exception I know of is the auto keyword, whose old meaning will be removed completely. That's safe because absolutely nobody used that keyword, and even if someone did, it's completely redundant anyway.
All the buzzt!
