Issue #18577 has been reported by takaram (Takuya Aramaki). ---------------------------------------- Bug #18577: Range#include? returns wrong result for beginless range with exclusive string end https://bugs.ruby-lang.org/issues/18577 * Author: takaram (Takuya Aramaki) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [x86_64-linux] * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- Exclusive range should not include the end value, but `(...'z').include? 'z'` returns true. `member?` and `===` behave in the same way, while `cover?` does not. This happens when the range is beginless and its end is string. ``` irb(main):001:0> (...'z').include? 'z' => true irb(main):002:0> (...'z').member? 'z' => true irb(main):003:0> (...'z') === 'z' => true irb(main):004:0> (...'z').cover? 'z' => false ``` -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
