I dunno what the standard says, but his confusion seems understandable
to me.

After all, he's not taking the address of a random local variable, but
of a _constexpr_ local variable, and I think the most natural way of
thinking about such a thing is "local in scope but global in extent,"
exactly like a local static variable.

The idea of a variable with a value explicitly fixed at compile-time,
but an address that changes at runtime seems just sort of weird...
