These tuples are created with make_tuple, which is given temporaries.
The make_tuple is in a function argument list.

A possibly overzealous static_assert in libc++'s std::tuple ctor
is firing in our 'Perform(make_tuple("hi"))' calls, so
we can't use its make_tuple here. Instead we will use
explicitly-constructed tuples constructed from non-temporary strings.
