1 // Issue #14893. Tests that casts from vectors don't behave strangely in the
2 // presence of the `_` type shorthand notation.
4 // Update: after a change to the way casts are done, we have more type information
5 // around and so the errors here are no longer exactly the same.
7 // Update: With PR #81479 some of the previously rejected cases are now allowed.
8 // New test cases added.
15 let x1 = X { y: [0, 0] };
17 // No longer a type mismatch - the `_` can be fully resolved by type inference.
