The explanation for embedding a struct which implements an interface is confusing.
The code for it restricts the container variable to one method: describe.
The example code in this patch uses the describer interface to specify a contract between a function and it's caller.
This explicitly gives a practical reason for using struct embedding or adding a method to an already embedded struct.
