Hi all ! Symbol lies about it's ability to respond_to? to #dup: irb(main):001:0> :s.respond_to?(:dup) => true irb(main):002:0> :s.dup TypeError: can't dup Symbol from (irb):2:in `dup' from (irb):2 Fixnum does the same thing. You might argue that the object *can* respond to :dup, except it's simply illegal to respond to it. Anyway, my feeling is that Symbol and Fixnum (probably Numeric) should not respond_to?(:dup). Thanks !
