WHAT? :) It even new's one?
But it works only for the ellipsis.
I wonder why the discrepancy...

Whoa. I never knew about this! It's ... I don't know what to
say. It
seems to be a cool feature, but it's also ... so scary.

It, in theory, doesn't allocate memory:
"An implementation may construct the object or array instance on
the stack. Therefore, it is an error to refer to that instance
after the variadic function has returned"
