I have been inspired by this, and I found this behavior
  irb
irb(main):001:0> mod =3D Module.new
=3D> #<Module:0xb7d8d024>
irb(main):002:0> mod.name
=3D> ""
ok understandable
irb(main):003:0> A =3D mod
=3D> A
irb(main):004:0> mod.name
=3D> "A"
most surprising
irb(main):005:0> B =3D mod
=3D> A
irb(main):006:0> mod.name
=3D> "A"
even more surprising
irb(main):007:0> B.name
=3D> "A"
??????
irb(main):008:0>

Well this kind of shocks me, is there an idea behind this which I am
missing?
If so could you please point me there.
Sorry for being so direct, but that seems to be in violation with "Ruby
should do what you expect it to do".

Cheers
Robert
