Subject: Is it a bug(about constant reference on dynamic class).

When I use a dynamic class, It can not reference constants.
See follow code and remark.
And is there any way to work around it?

#!/usr/bin/env ruby

class T
  def hello
    puts self.class.constants.join " "    # right, AAA
    puts AAA                              # right, 1
  end
end

T::AAA = 1

t = T.new
t.hello


c = Class.new do
  def hello
    puts self.class.constants.join " "    # right, AAA
    puts AAA          # error: uninitialized constant AAA (NameError)
  end
end

c::AAA = 123
inst = c.new
inst.hello
