//@ run-pass
#![allow(dead_code)]
// after fixing #9384 and implementing hygiene for match bindings,
// this now fails because the insertion of the 'y' into the match
// doesn't cause capture. Making this macro hygienic (as I've done)
// could very well make this test case completely pointless....
//@ pretty-expanded FIXME #23616
