.WHY not?

• Builtins can hold their own documentation

• Don't want to consume large amounts of memory for documentation

• Will use POD's P<...> tag form to dynamically include p6doc text

into setting upon request:

      # In Rakudo's src/core/IO.pm:

      #= P<p6doc/&print>
      sub print(|$) { ... }

      #= P<p6doc/&say>
      sub say(|$) { ... }

      #= P<p6doc/&note>
      sub note(|$) { ... }
