Still time for a few edits of that post?

Please emphasize the equally impressive comparison of the code 
necessary for the matrix multiplication.

glas.gemm(alpha, a, b, beta, c);

vs.

cblas.gemm(
     cblas.Order.RowMajor,
     cblas.Transpose.NoTrans,
     cblas.Transpose.NoTrans,
     cast(cblas.blasint) m,
     cast(cblas.blasint) n,
     cast(cblas.blasint) k,
     & alpha,
     a.ptr,
     cast(cblas.blasint) a.stride,
     b.ptr,
     cast(cblas.blasint) b.stride,
     & beta,
     d.ptr,
     cast(cblas.blasint) d.stride);
