While this syntax is quite helpful when you need to resolve name clashes, you are able to use

explicit interface implementation simply to hide more “advanced” members from the object level.

In this way, when the object user applies the dot operator, he or she will only see a subset of the

type’s overall functionality. However, those who require the more advanced behaviors can extract

out the desired interface via an explicit cast.
