[pairs.pair] "Requires Requires" requires fewer Requires #70
Description
Via cxxeditor@:
N3485 20.3.2 [pairs.pair]/16 says:
"Requires: Requires: is_constructible<first_type, Args1&&...>::value is true and is_constructible<second_type, Args2&&...>::value is true."
This typo is not repeated elsewhere in the Working Paper, as far as I can see.
