What does
new (&as_string) auto(other.as_string);
do where as_string is an std::string object?
I see that auto(other.as_string) constructs a new copy of other.as_string but what does the (&as_string) causes in combination with the new?

1Where did you come across it? Can you provide more context? – Pete Becker Dec 17 '16 at 17:19

@PeteBecker - The OP needs to clarify, but it seems like code form an implementation of a tagged union that contains a `std::string` member. – StoryTeller - Unslander Monica Dec 17 '16 at 17:21

@StoryTeller - shrug. There are lots of things it could be. – Pete Becker Dec 17 '16 at 17:24

@PeteBecker - True. But I think the language being used sort of implies it. Regardless, I'm more amazed with the use of `auto` here. A [toy example](https://ideone.com/AWdd8q) builds fine on GCC, and I wish the question was about *that*. – StoryTeller - Unslander Monica Dec 17 '16 at 17:27
