Erroneous code example:
-```compile_fail,E0624
+```compile_fail,E0627
mod inner {
pub struct Foo;
E0588, // packed struct cannot transitively contain a `[repr(align)]` struct
E0592, // duplicate definitions with name `{}`
// E0613, // Removed (merged with E0609)
+ E0627, // yield statement outside of generator literal
}
