I show the object_id just for clarity, to show that A and B is 
'referencing' or 'pointing' to the same object, although they do 
nothing. I thought I understand it until I try the example below for 
integers. Instead of showing errors, it gave very large bogus numbers, 
although results remain intact in the end. So, the answer to your 
question is that I don't. I think I might have missed out something 
here.

A = 10       => 10
B = A        => 10
B.freeze     => 10
A << 20      => 10485760
B << 40      => 10995116277760
A            => 10
B            => 10
A.object_id  => 21
B.object_id  => 21
