> That is wildly disingenuous.

assuming you're referring to numpy as to have anything to do with python spec, i totally agree with you. only it doesn't. so don't pytorch and pandas (and good so, poor python doesn't need any extra help to be completely f).

> you get an nxn identity matrix by...

no, man, that's how you get it. really advanced technique, kudos!

i get it by:

   id:{...}     /there are many ways to implement identity in k, and it's fun!
   id 3
  +1.00 +0.00 +0.00
  +0.00 +1.00 +0.00
  +0.00 +0.00 +1.00

but if you can keep a secret, more recently we've gotten so lazy and disingenuous in k land, and because we need them bloody matrices so often now, we just do it like so:

   &3
  +1.00 +1.00 +1.00
  +1.00 +1.00 +1.00
  +1.00 +1.00 +1.00

   =3
  +1.00 +0.00 +0.00
  +0.00 +1.00 +0.00
  +0.00 +0.00 +1.00

(but of course before we do that we first install python4, numpy, pytorch, pandas and polars - not because we need them, just to feel like seasoned professionals who know what they're doing)
