1 A tuple struct's element isn't a machine type when using the `#[simd]`
4 Erroneous code example:
10 struct Bad(String); // error!
13 When using the `#[simd]` attribute on a tuple struct, the elements in the tuple
14 must be machine types so SIMD operations can be applied to them.

22 struct Good(u32, u32, u32); // ok!
