Issue #21027 has been updated by nagachika (Tomoyuki Chikanaga). Fixed prism tests with updated snapshots at 5640fea8aada2380145375a7f9eac2b979fe1258. ---------------------------------------- Bug #21027: `not()` receiver should be `nil` https://bugs.ruby-lang.org/issues/21027#change-112568 * Author: kddnewton (Kevin Newton) * Status: Closed * Assignee: prism * Backport: 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONE, 3.4: DONE ---------------------------------------- `not` has a 0-argument mode, and the behavior differs from that of parse.y: ``` % RBENV_VERSION=3.4.0 ruby --parser=parse.y -e 'p not()' true % RBENV_VERSION=3.4.0 ruby --parser=prism -e 'p not()' false ``` This is because Prism interprets `not()` as `self.!` where parse.y interprets it as `nil.!`. -- https://bugs.ruby-lang.org/
