I realise my comment isn't clear, here's very simple code to show what i mean:

deprecated_constants = [:Fixnum, :TimeoutError, :Bignum, :FALSE, :TRUE, :NIL]
Object.constants.each do |constant|
  const_get(constant) unless deprecated_constants.include?(constant) 
end

the real code i have is more complex, but in essence this is the problem,
and deprecated_constants has to be maintained by me manually, which
will become out of date over time.

How about `class Object; deprecate_constant :Fixnum, :Bignum; end`?

* naruse supports: https://twitter.com/nalsh/status/773800491671101441
* akr objects: https://twitter.com/tanaka_akr/status/773817391218249729

I don't mind either way.
Do you have any comment about it?
