Remove_const vs. Object.remove_const vs. Object.instance_eval { remove_const }

In order to remove a class, I have to use Object.instance_eval
{ remove_const }

Why couldn’t I just use remove_const or Object.remove_const ?

Module#remove_const is private.

remove_const :Foo

is sent to the top-level object which is not a module.

Object.remove_const :Foo

fails because the method is private.

Object.instance_eval {remove_const :Foo}

is one way of getting around the privacy, another would be

Object.send(:remove_const :Foo}
