Is there anybody working on a linear algebra library for D2?

I've attempted this in the past, however, each time I manage to work up 
renewed enthusiasm I keep running into compiler bugs that put me off. My 
current feeling is I should sit back at wait for the language to mature 
a little.

However, once D does mature there are some neat tricks that would be 
possible in a matrix library. For a start you could easily build 
something like ATLAS with all the tuning parameters being passed as 
template parameters. Another neat trick might be verifying that a matrix 
is othoginal/unitary/whatever with invariants. Again a static if and a 
template parameter makes this feature really trivial to add.

As for things that aren't vaporware, 
http://www.dsource.org/projects/mathextra/browser/trunk/blade might be a 
good place to start.
