Transcription: You can include friend and member versions of an overloaded operator in a class. If two interpretations of an operator are defined, argument matching determines which version is called when the operator is used. The first argument of an operator that is implemented as a member function is the implicit this pointer. If friend and member function versions do not have different argument lists, an attempt to use the operator may fail to compile because it is an ambiguous function call.
