Detailed Description
Represents a call to a member function that may be written either with member call syntax (e.g., "obj.func()" or "objptr->func()") or with normal function-call syntax ("func()") within a member function that ends up calling a member function.
The callee in either case is a MemberExpr that contains both the object argument and the member function, while the arguments are the arguments within the parentheses (not including the object argument).
