Hi.

Is there a community convention that specifies which of the two methods,
`Object#clone` and `Object#dup`, should be overridden for the purposes of
deep-cloning?

On Stackoverflow, some say that `clone` should be overridden [1], while
others say that `dup` is the method to be overridden [2]. So I suspect that
there isn't such a convention.
