Issue #19559 has been updated by matz (Yukihiro Matsumoto). 私を含めた多くの人には #note-3 で @sawa さんが突然怒りだしたように見えます。少なくともその時点で「真剣に提案したものをエイプリルフールジョーク扱いするのは失礼だ」と感じたことは表明しておくべきではなかったでしょうか。また、自分が真剣に提案したものがエイプリルフールジョークだと思われて傷ついたという気持ちは理解できないことはないですが、だからと言って、それに対してコメントの削除なり、追放なりを求めるのはやりすぎだと思います。「私は真剣だった」、「そうでしたか」で終わるべき対話だったと感じています。 To many people, including me, @sawa seemed to suddenly get angry in #note-3. At least at that point, You should have expressed that you felt it was rude to treat a serious proposal as an April Fool's joke. Also, I can understand your feeling of being hurt by someone thinking that what you seriously proposed was an April Fool's joke, but that doesn't mean you should ask for the comment to be deleted or banned. I think it's overkill. I feel that the dialogue should end with “I was serious” and “OK”. ---------------------------------------- Feature #19559: Introduce `Symbol#+@` and `Symbol#-@`, and eventually replace boolean arguments with symbols https://bugs.ruby-lang.org/issues/19559#change-102971 * Author: sawa (Tsuyoshi Sawada) * Status: Rejected * Priority: Normal ---------------------------------------- I propose to define `Symbol#+@` and `Symbol#-@`, so that we can add positive or negative polarity to symbols. A possible implementation can be equivalent to what can be achieved by this: ```ruby class Symbol def -@; "-#{self}".to_sym end def +@; self end end ``` The intention behind this is to, eventually, replace boolean positional or keyword arguments with symbols so that, instead of this: ```ruby "foo".methods(false) gets(chomp: true) Integer("2.3", exception: false) ``` we can write like this: ```ruby "foo".methods(-:inherit) gets(+:chomp) Integer("2.3", -:exception) ``` -- https://bugs.ruby-lang.org/
