Funky constant lookup change between MRI 1.9.2 vs. 1.9.3
# see this blog post for differences between 1.8.7 vs 1.9.1 vs. 1.9.2: http://jfire.posterous.com/constant-lookup-in-ruby
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
