-// Test a case of a trait which extends the same supertrait twice, but
-// with difference type parameters. Test then that when we don't give
-// enough information to pick between these, no selection is made. In
-// this particular case, the two choices are i64/u64 -- so when we use
-// an integer literal, we wind up falling this literal back to i32.
-// See also `run-pass/trait-repeated-supertrait.rs`.
