A variation of that is what numpy and Eigen use. In numpy, for the array class '*' is element-wise by default and the function np.dot is matrix multiplication. For Eigen '*' is matrix multiplication by default while the (member) function cwiseProduct is element-wise. One the one hand, this is more readable than matlab or R in terms of having a clear default. (Whereas in matlab you have to be careful to distinguish between '.*' and '*', or '*' and '%*%' in R.) But it's both hideous to look at and to type. An improvement over .add or .times in Java matrix libraries, but far from Nirvana. I'm hoping D can do better.
How would you like the syntax to be, in an ideal world?
