Admittedly this came about as a result of some poor design on my 
part, but I don't get what you're saying about auto. I thought 
auto was supposed to relieve the cognitive load of manual type 
identification. Without it, std.algorithm would be a pain to use. 
My brain doesn't intuitively tell me that std.algorithm.filter 
returns a FilterResult, but I can use it effectively with auto.
