From: marcandre-ruby-core@... Date: 2020-11-21T07:45:19+00:00 Subject: [ruby-core:101001] [Ruby master Bug#10845] Subclassing String Issue #10845 has been updated by marcandre (Marc-Andre Lafortune). I'll ask the same question I've asked before... Why not deprecate this first? This gives time to Rails to issue a simple update to the versions that are supported, and in a year or two the behavior can change without breaking anything. Fixing things is good, but there is no urgency to fix this. ---------------------------------------- Bug #10845: Subclassing String https://bugs.ruby-lang.org/issues/10845#change-88669 * Author: sawa (Tsuyoshi Sawada) * Status: Closed * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * ruby -v: 2.2 * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN ---------------------------------------- If I make a subclass of `String`, the method `*` returns an instance of that class. ~~~ruby class MyString < String end MyString.new("foo").*(2).class #=> MyString ~~~ This is different from other similar operations like `+` and `%`, which return a `String` instance. ~~~ruby MyString.new("foo").+("bar").class #=> String MyString.new("%{foo}").%(foo: "bar").class #=> String ~~~ I don't see clear reason why `*` is to be different from `+` and `%`, and thought that perhaps either the behaviour with `*` is a bug, or the behaviour with `+` and `%` is a bug. Or, is a reason why they are different? -- https://bugs.ruby-lang.org/ Unsubscribe:
