Creating a new exception class is actually trivial  in D, we 
create new types all the time without even thinking about it 
almost every time we hit `!`, and could be even more so with some 
library helpers.

Catching the type when it doesn't have an outside name isn't as 
easy, but the randomly created types can still inherit from some 
base class that is caught, but the templated/generated 
implementation overrides various interface functions to provide 
more detailed, rich information (and, of course, you CAN still 
catch it specifically if you really wanted to).
