Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Defeat Zeitwerk's re-autoload hook when we re-eval a file in place. Walking the source AST for top-level class/module names and calling const_get on each tells Zeitwerk "this constant is loaded" so our re-eval does not lose state (e.g. @_included_block) to a follow-up autoload.
