From: "akr (Akira Tanaka) via ruby-core" Date: 2023-09-21T11:47:51+00:00 Subject: [ruby-core:114862] [Ruby master Feature#13933] Add Range#empty? Issue #13933 has been updated by akr (Akira Tanaka). I described that this is difficult to implement in https://bugs.ruby-lang.org/issues/19839#note-18. The problem is not only with -Float::INFINITY. There are many minimum values other than -Float::INFINITY : [], "", true, false, Object.new, etc. Of course, a user may define a class with a minimum value. Range#empty? should work with them. ---------------------------------------- Feature #13933: Add Range#empty? https://bugs.ruby-lang.org/issues/13933#change-104710 * Author: ted (Ted Johansson) * Status: Open * Priority: Normal ---------------------------------------- Range already responds to #size. It would be nice if it also responded to predicate #empty? :-) -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
