I suppose that any method which works is fine. The advantage with a
more preprocessor-like methodology is that it doesn't incur two
function calls. Shipping delegates around to functions is nice for
self-modifying code, but that's overkill for this sort of
functionality. It has a fairly clear use for making complex thread
synchronization look prettier, but if you're doing that sort of fancy
footwork to begin with, then speed is probably a driving motive (or
you're making code that's more complex than it needs to be. ;) )

But again, like I said, any method which works is probably fine. And
possibly DMD is good at inlining such things.
