numpy is much more than a wrapper around a BLAS dll. BLAS implements three sets of operations: Level 1: unary and binary vector vector operations, one transform. Level 2: Matrix vector operations. Level 3: Matrix matrix operations (most famously the dgemm routine). Perhaps some blas implementations offer more features, but that would defeat the purpose of a standard interface.
