STATIC.md

The purpose of this document is to outline a possible path for further evolution of the private state proposal. The idea is to make sure that this proposal is consistent with the described evolution path, but to keep these additional features for follow-on proposals. This proposal does not change the semantics of any working code from the main proposal in this repository.

Static private field outline

It should be possible to add private static fields, as well as methods, per this explainer. The syntax could look like this:

class MyClass {
  static #foo = 1;
  static #bar() { ... }
};

Static private methods and fields would be visible only within the body of the class. They have one value, only for the class they are defined in, not for subclasses as well. The semantics could be defined two ways:

• These are just lexically scoped variables which have special syntax to make them scoped to the class
• The class actually gets these as private fields and methods, with those same semantics as for instance private fields

I don't think there are observable differences to these semantics.
