Overview

Re-evaluating an ‘ActiveSupport::Concern` module raises “MultipleIncludedBlocks” because AS::Concern records the block source location on the first include/prepend call. Before a re-eval we clear the `@_included_block` / `@_prepended_block` ivar on modules whose block came from the file we’re about to re-eval.
