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.

C - works with everything does everything. Not that fun, somewhat annoying.
C++ - works with almost everything. Very gay but works and is often better modularized than C
D - Bits of C & C++ combined into a language which looks like both C and C++ yet lacks the compatibility and tool support to make it truly useful. Doesn't even include interesting or useful features let alone truly support programming in the large.

D is an utter failure and you waste everyone's time talking about. Just shit C++ through a macro pre-processor and you have D. Big fuckin whoop.
