Which version of Ruby did the clone method begin to work on TrueClass, Fixnum and Symbol and others?

Hi All,
In version 2.2, when I do something like true.clone, I get a runtime/type
error. In 2.4 and later this works.
Does anyone know when this occurred. I would like it for my install docs.

Thanks in advance.
Cheers,
Ed

Hi Ed,

the change occurred in 2.4.0

as demonstrated by this Travis test matrix: https://travis-ci.org/igneus/
ruby-clone-test

the code run there: https://github.com/igneus/ruby-clone-test

I wasn't able to identify a respective changelog entry in https://github.
com/ruby/ruby/blob/v2_4_0/NEWS , though. (I didn't attempt to traverse git
history.)

Regards,

Jakub

Hi.
Thanks for the info. Never occurred to me to check the Travis CI stuff.
Mostly my code works back to 2.2.x and I was doing s a specific kind of
deep clone. So I had to writ some ugly guard cases around these immutable
types.

Thanks again.

Regards, Ed

Cheers,
Ed
