There's an interesting cognitive impercetion phenomena here, 
that's worth studying and not ignoring. From the little evidence 
here, it seems that D programmers want to use UDAs instead of 
templates for those purposes. Possibly because UDAs look more fit 
(despite you rightfully say they aren't).
