Subject: [ruby-core:17918] String methods on subclasses return "uninitialized" objects

Hi,

During the work on RubySpec tests, we had an interesting discussion on
String methods behavior which we'd like to double-check with
ruby-core.

Say, we have a subclass of String, and then invoke #split on that
subclass instance. That method will return instances of that subclass
as well, as expected, but it seems that the #initialize method in not
really invoked at all. Is that intentional or accidental?

It seems to me that if there is a custom initialize method written for
that subclass, it is there for a reason (maybe, all objects require
some customization), but in case of many String methods, the created
instances are not properly initialized. Opinions?

Thanks,
