I was discussing the current routing mechanism with my colleague  
Romek the other day. The Rails approach to routing is fine for simple  
cases, but as the REST architecture encourages arbitrary resource  
nesting Rails could really do with something in the way of a classic  
production or inference system - maybe even a Prolog-style routing  
DSL. If only I had the time to investigate further..!
