I can confirm that does work.

That being said, the amount of acrobatics that had to be performed to make the
templates involved not directly refer to the type at hand is somewhat
frightening.  It reminds me of implementing something by using lambdas several
layers deep.  This stuff probably has a limit, if not in what it can do, then
in the cognitive load on the programmers using it.  Too bad macros were
scrapped for D2, huh?
