Issue #20324 has been updated by k0kubun (Takashi Kokubun). Backport changed from 3.0: DONTNEED, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: REQUIRED to 3.0: DONTNEED, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONE This seems to have been backported to `ruby_3_3` at commit:6d6818883b8. ---------------------------------------- Bug #20324: `(1..).overlap?('foo'..)` returns true https://bugs.ruby-lang.org/issues/20324#change-108496 * Author: kyanagi (Kouhei Yanagita) * Status: Closed * ruby -v: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [arm64-darwin22] * Backport: 3.0: DONTNEED, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONE ---------------------------------------- While thinking about finding the intersection of two ranges, I found that `(1..).overlap?('foo'..)` returns true. In the current implementation, it seems that `(a..).overlap?(b..)` or `(..a).overlap?(..b)` returns true regardless of what `a` or `b` are. However, I think it should return true if and only if `a` and `b` are comparable. (What is the intersection of `1..` and `'foo'..`?) -- https://bugs.ruby-lang.org/
