But it seems a few were missed, notably mentioned in https://bugs.ruby-lang.org/issues/12979#note-15. Rational and Complex seems obvious candidates for supporting #dup/#clone returning itself as well since they are pretty much values. Rational and Complex are currently not frozen though (see #13983). Kasper (in the comment linked above) also mentions Method, but I think that's worth its own issue as it's no longer simple numeric values. Note that BigDecimal is currently not frozen, but supports #dup/#clone (returning a new instance) (see #13984). -- https://bugs.ruby-lang.org/ Unsubscribe:
