But BLAS is much more than 3 loops for matrix-matrix multiplication.

Why turn your back on all the carefully crafted optimizations?

BLAS is great and must be used whenever possible. That was not my point.

I don't want to turn my back on the beautiful loop notation. For some algorithms, the loop notation is clearer than any "vectorized" version. It is absurd that the language penalizes you for that. Loops are alright.
