  --> $DIR/issue-54779-anon-static-lifetime.rs:32:9
   |
LL |         cx: &dyn DebugContext,
   |         --  - let's call the lifetime of this reference `'1`
   |         |
   |         `cx` is a reference that is only valid in the method body
...
LL |         bar.debug_with(cx);
   |         ^^^^^^^^^^^^^^^^^^
   |         |
   |         `cx` escapes the method body here
   |         argument requires that `'1` must outlive `'static`
