Subject: Re: class returns value without method or attribute

I like the idea of using inspect, will this also allow me to assign 
value like:
money = Money.new
money = 5

Also do I need to add a method for + and -, is there not a module like 
Comparable that I can mixin to get this functionality?

Are there any other typical methods I should be adding? Excluding the 
money specific stuff I have to_s.

Many thanks for all the replies they have been really helpful.
