I think there might be a disconnection in this thread. D only,

There are hardware vendor and commercial libraries that are
heavily optimized for particular hardware configurations. There
is no way a D-only solution can beat those. As an example Apple
provides various implementations for their own machines, so an
old program on a new machine can run faster than a static
D-only library solution.
What D can provide is a unifying abstraction, but to get there
one need to analyze what exists. Like Apple's Accelerate
framework:

That goes beyond BLAS. We also need to look at vDSP etc. You'll
find similar things for Microsoft/Intel/AMD/ARM etc…
