// Test an interesting corner case that ought to be legal (though the
// current code actually gets it wrong, see below): a fn that takes
// two arguments that are references with the same lifetime is in fact
// equivalent to a fn that takes two references with distinct
// lifetimes. This is true because the two functions can call one
// another -- effectively, the single lifetime `'a` is just inferred
// to be the intersection of the two distinct lifetimes.
