FYI an infinite range is defined to have

     struct Infinite {
         enum empty = false;
     }

You know it will never be empty at compile time.

Being able to read and understand a piece of code has nothing to 
do with knowing exactly how it achieves its task or what the code 
the machine will be running. If there is a bug, then you'll need 
to dig into it. If there is a performance problem you've 
identified then you'll be looking at it, but in general those 
aren't important to understanding what the code does.
