I like D, it's fascinating and powerful language. It made it even more curious when I watched Tsodings video on D. One thing that came to my mind when reading the article is that things like int.init instead of 0 and $ as shorthand for array.length does add to the mental load.

One good memory I had is a couple of years ago when I built a little forum using D. Man the site was blazing fast, like the interaction was instant. Good times.
