The (probable) final feature-set for the C++17 ISO standard has been publicized, and among these features is something called structured bindings:
auto [a,b] = /* something like a tuple */;
Is there a compiler that implements this feature? Preferably I'd like something online e.g. via IDEONE or Wandbox; failing that I'd like something that will work on Debian Linux, and in the last resort I can use Windows.
