Bug #10845
Updated by mame (Yusuke Endoh) about 5 years ago
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: 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?
