The problem is that other math operators used on matrices are only in element-wise form (+, -, /, *), so, usual math operators are enough for this. But multiplication can be element-wise or dot-product, hence, we need two separate operators.
I saw Swift guys using <*> for dot-product, seemed like a good choice for me.
