Subject: Change in constant lookup path from 1.9.2 vs. 1.9.3

Hello all,

I'm observing a chance in the way constants are looked up between
1.9.2-head and 1.9.3-head. Please see below (and comment if it's
expected or a regression?):

module M
  X = 100

  def m1
    puts X
  end
end

class C
  extend M

  def self.m2
    puts X
  end
end

def C.m3
  puts X
end

C.m1 # works in 1.9.2 and 1.9.3
C.m3 # works in 1.9.2, generates missing constant exception in 1.9.3
C.m2 # generates missing constant exception in 1.9.2 and 1.9.3
