You'll find the same behavior in every type of function, and you'll get 
used to it. Numbers, booleans, and at least one other class that I don't 
remember at the moment are passed this way. I'm not sure about 
subclasses of the aforementioned, but I think they are still passed by 
value (i.e., all Numeric classes are so passed). If you need to pass a 
different class by value, just pass my_variable.dup instead.
