Is it possible to use tokens as template parameters?

Me no understand. :) I see it as an example of how opDispatch is 
privileged. It nicely parses a token and provides it as a string. 
Templates don't have that. I want to be able say

   std.typecons.Flag!foo f;

instead of

   std.typecons.Flag!"foo" f;
