The idea is that context is something you pass along in each of your  
calls.  If your function body is a simple call, then it does not  
affect the context; the callee gets the same context as you are getting.

So one can say that "want" is really one of the contextual variables  
that gets reassigned every time a function is called when a  
particular type is expected.
