From: "Eregon (Benoit Daloze)" Date: 2022-02-21T12:09:43+00:00 Subject: [ruby-core:107686] [Ruby master Feature#18595] Alias `String#-@` as `String#dedup` Issue #18595 has been updated by Eregon (Benoit Daloze). :+1:, `dedup` seems an helpful name and it is chainable. Also if this is ever called from some other language, e.g., C extensions, then `rb_funcall(str, "dedup")` is much clearer than `rb_funcall(str, "-@")`. ---------------------------------------- Feature #18595: Alias `String#-@` as `String#dedup` https://bugs.ruby-lang.org/issues/18595#change-96605 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- This is a rescoped feature request for https://bugs.ruby-lang.org/issues/16295 ### Rationale [Unary operator have some precedence oddities](https://bugs.ruby-lang.org/issues/16150#note-39) (@headius) This often force to use parentheses, which is awkward and breaks the chaining flow. It's really not obvious what it does. I submitted many pull requests to various open source projects to reduce their memory footprint, and I am constantly asked what it does and I have to point to the `String#-@` documentation. [The last example was 3 days ago](https://github.com/dry-rb/dry-schema/pull/399#issuecomment-1043963073). I believe that `String#dedup` would help users discover this feature, and in projects where 3.2 is the oldest supported version, it would allow for much clearer code. ### Proposal It's all in the title: Alias `String#-@` as `String#dedup`. Or maybe even rename `String#-@` as `String#dedup`, and make `String#-@` the alias? -- https://bugs.ruby-lang.org/ Unsubscribe:
