Embedding
When an outer type ALSO defines a method with the same
name as a promoted one, the outer's method overrides. To
call the inner's method explicitly, you go through the
embedded type's NAME as a field path:
d.${word}.Describe().
Type the field name you'd use.

About this theme
Struct embedding gives you composition without inheritance. Embed a type as an unnamed field and its methods get promoted onto the outer struct. This is how Go does "extend a type" — by containing one. The rule: prefer composition; Go literally doesn't give you inheritance to misuse.
