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.

Replace a loop body with a bare raise: while c; body; end becomes while c; raise; end.

A survivor means no test ever enters the loop, so the body is either dead or reached only by paths the suite never exercises. The raise terminates the loop on its first iteration, which is what makes this safe where body-to-nil is not: nil-ing a body that advances the predicate spins until the per-mutation timeout (EV-170m.7).
