It is D2, but there's a port of it to D1 in the "std2" project.
http://www.dsource.org/projects/std2/browser/trunk/std2/std2/typecons.d

It's not one of the modules I've used, though, so I can't recall if it
actually worked or not.  (For some reason I didn't put it in the list
of "ported modules" here http://www.dsource.org/projects/std2. --
could be I just forgot to update that list after porting it.)
