Re: info about OOP interpreter design and functions management?

Perhaps a look back at the start of C++ will help. Classes can be
treated like other data structures (struct, record...), so it's
sufficient that your interpreter can handle structured data types. At
least you'll find more about the handling of structured data types in
interpreters, than about the handling of full blown objects and
classes.

Methods are functions in disguise, which take their object as a hidden
argument. A statement like:
    obj.meth(arg)
then can be implemented like a more traditional procedure call:
    meth(obj, arg)


Things become more complicated when you want to implement polymorphism,
inheritance and virtual methods.
