I'm still waiting for std::pseudovector<T>

It aggravates me too, however, considering that the definition of a tensor according to mathematicians is an element of the tensor product of two vector spaces (or whatever other objects you can tensor together), and according to physicists would be an object which transforms like a tensor, I’m somewhat sympathetic. Neither definition sheds any light on what a tensor is to anyone who doesn’t already understand what a tensor is, and I’m convinced that the moment one understands what tensors are they lose the ability to explain what tensors are.

I have an academic mathematics background and I'm perfectly OK with this.
