[Proposal] Simple Class Inheritance

[gregsn]

Quest #11

When making libraries available for VL you sometimes need to inherit from a base class. In order to do so can we just start with a reduced feature set like so:

• ability to list a class in the supertypes
• ability to overwrite virtual or abstract methods / operations by just adding them to the list of operations (they then grab the signature of the base class regarding their inputs and outputs)
• ability to call base.Foo

we skip:

• sealing classes
• defining abstract classes
• defining virtual or abstract operations
• defining virtual or abstract properties
• protected and private keywords
• new keyword
• overriding a certain overload with a certain signature. Can we assume that the name of the operation is enough to find the method that shall be overridden?

open questions:

• how to treat virtual or abstract properties? We don't have actual .Net properties. We only have setters and getters = patterns on how to name operations and we have fields.
• how does that relate to the proxy system? Can we disable it for those types if it becomes an obstacle?
