=== by default calls == unless you specifically override it in your 
implementation.

Module overrides it (which means that Class overrides it as well).

I think it's probably safe to say that === is in the same context as kind_of?, 
at least for classes:

irb(main):009:0> NilClass === nil
=> true
irb(main):010:0> nil === NilClass
=> false
