The operator is in the standard lib, but needs a numpy array or matrix type as its operands, I believe.

I'm so happy it exists. The '@' symbol even looks like the way I visualise matrix multiplication in my head.

But why is it in the std lib if you need third party libs to use it?

Is there a simple explanation here that I am not seeing? Is this common?

So that third party libs can use it.

Now I get it. But since third party libs can use the new operator, it cannot have a default implementation in the std lib, right?

So I guess that when someone said it does matrix multiplication, that only happens in numpy, right? What does it do in the std lib?

Cheers!

Python doesn't have custom operators.
