Enforce private/protected visibility

• Type: idea
• Status: rainy-day
• Owner: —
• Opened: 2026-06-06 (from todo.md / limitations)

Motivation

Class visibility sections (private/protected/public/published) are parsed because published drives RTTI, but private/protected access is not enforced. Enforcing it enables no new programs, so it is intentionally deferred until compatibility pressure justifies it.

Scope (if adopted)

• Reject out-of-scope access to private/protected members.
• Keep published/RTTI behavior unchanged.
• Decide whether strict-mode-only or always-on.

Status

Idea / parked. Adopt only when real source fails to compile elsewhere because we don't enforce this.
