Review Mojo's priorities

• [X] I have read the roadmap and priorities and I believe this request falls within the priorities.

What is your request?

Open source tensor module

What is your motivation for this change?

When I use the tensor type, some strange errors appear. I am curious to know the components of the tensor for better, smoother, and easier use. If you mind, that's fine.

Any other details?
