<pre>Hello,
code like the following seems to compile using exactly the tuple::operator=
overloads from the standard, but not with the clever refactorization in libc++.
I think A is not detected as tuple_like.
#include <tuple>
struct A : public std::tuple<int, double> {};
int main() {
A t;
int i;
double j;
std::tie(i,j)=t;
}</pre>
