Um. OK. It turns out it's easier to make the compiler eat that than it is 
to make it reject it. Also sometimes it's handy to have it look at only the 
last cases (I think that's what it does). As an example, in generated code. 
Another example of this is in unix command line apps that often have on/off 
flag pairs that can be mixed ad-nauseum because they grab flags from several 
different sources that need to override each other.
