The implementation of
Enum#includes?is too lax and returns true if any common bit is set (#13160 (comment)). This patch checks that all bits are set.@HertzDevil Suggested this might need to be merged together with #13160, but I would see it as fix that makes sense on its own. We can pool them together, but I don't think it's strictly necessary...?
The behaviour of
Nonemay need some explanation. The current implementation always returnsfalsewhen the parameter isNone(even forNone.includes?(None)). Some code may depend on this quirk, including the implementation ofEnum.each(hence this needed to be fixed as well).I wouldn't expect much code to be affected and it's probably best to apply this change regardless. It is a bug and fixing it may have a small chance of breaking someone's code.
