[ruby-core:83855] [Ruby trunk Feature#14123] Kernel#pp by default

Issue #14123 has been updated by k0kubun (Takashi Kokubun).


> also breaks when running ruby chrooted

Regardless of proposed implementation, `require 'pp'` wouldn't work if chrooted. I couldn't understand why it's problematic.

> Regarding visibility, #pp should be a module_function of Kernel like #p.

It's already module_function, isn't it?
 https://github.com/ruby/ruby/blob/246c986eac342ae7bbf05f3be97c92fc71f9d21d/lib/pp.rb#L26

Thus following one would be sufficient.

~~~ ruby
module Kernel
  def pp(*objs)
    require 'pp'
    Kernel.pp(*objs)
  end
end
~~~
