The resulting ambiguity of this is referred to as object schizophrenia. Translating the implicit this into an explicit parameter, the call (in B , with a a delegate) a.foo() translates to A.foo(b) , using the type of a for method resolution, but the delegating object b for the this argument.
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.
A common example of ambiguity in computer programming languages is the dangling else problem. In many languages, the else in an If–then(–else) statement is optional, which results in nested conditionals having multiple ways of being recognized in terms of the context-free grammar.
The listed languages are designed with varying degrees of OOP support. Some are highly focused in OOP while others support multiple paradigms including OOP. [1] For example, C++ is a multi-paradigm language including OOP; [2] however, it is less object-oriented than other languages such as Python [3] and Ruby. [4]
In object-oriented programming, the open–closed principle (OCP) states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; [1] that is, such an entity can allow its behaviour to be extended without modifying its source code. The name open–closed principle has been used in two ways.
