I am brand new to Ruby, and I have been reading Programming Ruby.
However, I do have a question, having struggled for some time.
How does the Hash work. I am trying to create a multi-dimensional
hash. For example,
h = Hash.new
h['1']['2'] = '10' gives error undefined methos '[]=' for nil
h['1'] = '10' is OK
h['1']['2'] = '10' is OK too
print h gives 110nil - this I don't understand

Hope somebody can help me. Thanks.
