That's exactly what you get with an uncaught exception (remember 
the druntime catches exceptions by default, turn that off to get 
this behavior). One of my favorite parts of them and i'm not sure 
how a sumtype thing would compare. I guess you could set a 
conditional breakpoint.

I'm pro-exception but I also do think D should go ahead and move 
forward with making the return value type thing work better. If 
we do it right, the supporting features can be useful in other 
contexts too.
