[Numpy-discussion] Proposal: Chaining np.dot with mdot helper function

[Eelco Hoogendoorn]

If the standard semantics are not affected, and the most common
two-argument scenario does not take more than a single if-statement
overhead, I don't see why it couldn't be a replacement for the existing
np.dot; but others mileage may vary.
