Sounds good:
- a matrix multiplication in phobos that is faster than a naive
implementation but does not try to beat BLAS gemm.
- a dub LA library around BLAS. There is
http://code.dlang.org/packages/cblas but it seems to be not much
more than dstep + cblas.h

Don't know, I perhaps try.
I have a working prototype of a BFGS non-linear optimizer
currently calling BLAS via array.ptr and the vague plan to make
it opensource. If that ever happens, a LA library around BLAS
would be a great co-product.
