[ruby-core:83853] [Ruby trunk Feature#14123] Kernel#pp by default

Issue #14123 has been updated by jeremyevans0 (Jeremy Evans).


I'm not opposed to this feature, but the proposed implementation is not thread-safe, and also breaks when running ruby chrooted.  If `Kernel#pp` is implemented, I request the implementation be thread-safe and that it fall back to `Kernel#p` if requiring `pp` fails.
