There might have been a 'personal' need but I don't think that makes
it a *real* need. The ugly code was just the way it is done. Changing
it was like saying "I don't like the way Ruby lets me assign strings
to a variable so I am going to change it." and then you come up with
something that replaces my_var = 'my string'.
