Defined in:
lib/mutineer/mutators/boolean_literal.rb

Overview

Mutates true/false AND nil literals — "boolean_literal" is the spec's name for the family (§4), so nil is in-scope by design even though it is not strictly a boolean. true<->false, and nil->true (nil->true catches more return-value gaps than nil->false). Rewrites the whole node location; these nodes have no sub-token location.

Clean-room: from the spec's operator table, not the mutant gem.
