ILight.Power() was typoed as ILight.PowerStatus.

Type of issue

Typo

Description

In this section, ILight was added Power() with default implementation:

public interface ILight
{
    //...
    public PowerStatus Power() => PowerStatus.NoPower;
}

However, the following sections are indicating it as PowerStatus.

Avoid overriding the same method ... an override of PowerStatus, ....

Both the diagram right below the above paragraph and the next paragraph after the diagram contain the same typo.

The preceding diagram illustrates the ambiguity. OverheadLight doesn't provide an implementation of ILight.PowerStatus. Both IBlinkingLight and ITimerLight provide overrides that are more specific. A call to ILight.PowerStatus on an instance of OverheadLight is ambiguous. You must add a new override in OverheadLight to resolve the ambiguity.
