https://github.com/jruby/jruby/issues/277 asks this question:

results = 10000.times.map do
  chars = ('A'..'Z').map(&:to_sym).shuffle

  cls = Class.new do

    chars.each do |chr|
      define_method(chr) {}
    end

  end

  chars == cls.instance_methods.take(26)
end

p results.all?{|o|o.equal? true} # => true on MRI
