is D worth learning?

The D programming language... is it worth taking my time off my current projects to learn?

I've actually found one independenet game programmer who uses D -- source code included with this halfpipe shooter called Torus Trooper is written entirely in D.

But will this language ever really take off enough to warrant learning it?  There aren't even any books on it, and that may be a bit of a handicap in really getting mentally "into" it.

Okay, two things:
a) The one problem the implementations of D definitely do not have is performance.
b) Focusing on performance is going to get you in trouble.

Honestly, if performance is your main concern, and you're coming from a Common Lisp background, you might be better off learning Ocaml. Good performance, more support than D, and more powerful than C++.

That's not to denigate D. I think it's a very promising system language, but it's only for hobbyists at the moment.
