Description

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

I vote no! Imposing order upon the method table requires all implementations to use an ordered data structure here where unordered structures might serve better. Also consider that reflective method access on most other platforms does not guarantee any ordering.
