+// SI-6675 DEPRECATED AUTO-TUPLING BECAUSE BAD IDEA -- MEAMAXIMACULPA
+// TODO: remove this test case in 2.12, when the deprecation will go into effect and this will no longer compile
+// slightly overkill, but a good test case for implicit resolution in extractor calls,
+// along with the real fix: an extractor pattern with 1 sub-pattern should type check for all extractors
+// that return Option[T], whatever T (even if it's a tuple)
