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