std::ignore doesn't work in the context of structured bindings. And even if it did, "we already have this" has never stopped the C++ committee from adding something before :)
Yes, the "skill" of the commitee to discuss some feature for a really looooooong time and then come up with a solution which is going to be (half) fixed in the next standard always astonishes mé :).
I guess with C++38 we'll get a `always_definetly_ignore_this_wothout_any_diagnostic_whatsoever`.
