Private Class Feature Parser

Build a parsing helper that accepts JavaScript source containing private class fields and methods and returns a summary of those members without transforming the code.

Capabilities

Parses private instance members

• A class declaring a private instance field #count and private method #inc() is parsed without error, returning privateMembers entries for both with static: false and correct kinds. @test

Parses private static members

• A class declaring static private field #registry and static private method #touch() is parsed without error, returning entries marked static: true for both members. @test

Rejects invalid private usage

• Referencing #secret outside any class body raises a syntax error that includes the private name in the error message. @test
