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.

and you fail at speed when you write in D. C++ has compilers with optimization, D has nothing. D only has single-inheritance which is useless for some tasks. D only has a closed-source shitty compiler. D fails.
