Good to know I'm not the only one who's had to working around this. :-P Considering how D has unit testing and contract programming built-in already, I'm still a bit surprised it doesn't have assertions and expectations that are actually useful for people doing heavy unit testing.

deferAssert is interesting, but it seems to require a lot of boilerplate. The combination of mixin and template syntax is a bit kludgy, heh.
