Works as expected, works as documented, works perfectly. I'm using it for tied array type stuffs, with the tie semantics. Awesome, easy, and so very useful.
Watching coverage numbers slowly climb is deeply satisfying in a horribly nerdy way. Seeing colors change (for the better) is even nicer. D::C fits really well into my development style of implementing things one tiny piece at a time and testing for goodness as I go. So, so good.
Good lord. This is such a good idea, but it's implemented so badly. Iterating over a 13k RSS feed from the BBC chewed up 135M of memory before I killed it. Aside from that, it's really quite nice.
I can find no flaws. It just does its job, exactly as advertised, in a straightforward manner. Yay!
