Have there been any papers written on implementing design patterns in
delegation/object based languages? I'm interested in how delegation or
object based inheritance can simplify design. For example these
patterns from the Gamma, et al book seem to become non-issues in such a
Prototype - built in to object based languages.
Singleton - built in to object based languages.
Chain of Responsibility - can be done easily by delegating to next
object in chain.
State - can be done easily with an assignable parent slot.
Strategy - can be done easily with an assignable parent slot.
Decorator - can be done easily with an assignable parent slot.
Proxy - proxy can delegate to the other object.
But I am also and perhaps more interested in design idioms that
naturally arise out of differential programming, beyond the few that
are mentioned in the papers on the Self site.
