I think you're getting hung up on this part:

Yes, v and v2 are equal. But that is irrelevant with regards to your 
hash.

Now, if you had to objects that were identical (not equal, but 
identical) then it would work:

s1 = 'string'
s2 = s1

h = Hash.new

h[s1] # 'string'
h[s2] # 'string'

s1.upcase!

h[s2] # 'STRING'
h[s1] # 'STRING'

Hope that helps.
