eye() returns an array with ones along the kth diagonal, and zeros elsewhere, and is implemented as per the array API standard specification.

The following input dpt.asnumpy(dpt.eye(5, k=1, dtype='c8', order='F')) on WSL causes my driver to glitch. I will retry, but the input hangs uninterruptibly too.
