[ruby-core:100995] [Ruby master Bug#10845] Subclassing String
From:

ruby-core #100995
Issue #10845 has been updated by jeremyevans0 (Jeremy Evans).
Status changed from Open to Closed
Thanks to @matsuda's work showing that Rails already does something very similar and only needs a small patch to work with this, I have committed the patch at commit:58325daae3beefda13ed100782cd19a89cc68771. If it causes any problems or breakage we are unwilling to accept, we can revert the patch.
----------------------------------------
Bug #10845: Subclassing String
https://bugs.ruby-lang.org/issues/10845#change-88662
* 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?
