Why do you think this is needed? Why (there may be some reason! but you
have not told us what that is) can your program not just::

    print(dinner['Starters'])
    print(dinner['Main Course'])
    print(dinner['Desert'])

The above code produces this output, without any need for binding new
names. So what is it you are actually trying to achieve, and why do you
think the new bindings are necessary?
