Perfectly, thank you. This should be preserved for all time :) Bottom
line, don't define those methods unless you are 100% compatible with
the type they reference, and generally they're only intended for use
from core methods that need to get those types of objects.

So the proposal is intended for userland conversion methods like to_a,
to_s, to_yaml, and friends.
