No. I’m not sure what you find objectionable in my (seriously) not being clear whether your proposal was a serious one or an early April Fool’s proposal, because it could have been either one. As a serious proposal, I dislike it. As joke proposal, I think that it’s entirely funny. ---------------------------------------- Feature #19559: Introduce `Symbol#+@` and `Symbol#-@`, and eventually replace boolean arguments with symbols https://bugs.ruby-lang.org/issues/19559#change-102887 * 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/
