LL | impl Copy for &'static mut Bar { }
   |               ^^^^^^^^^^^^^^^^ type is not a structure or enumeration

error[E0117]: only traits defined in the current crate can be implemented for arbitrary types
  --> $DIR/E0206.rs:3:1

LL | impl Copy for Foo { }
   | ^^^^^^^^^^^^^^---
   | |             |
   | |             this is not defined in the current crate because arrays are always foreign
   | impl doesn't use only types from inside the current crate
   |
   = note: define and implement a trait or new type instead

error: aborting due to 3 previous errors
