That's what I did. The technical matter was being ignored.

I already explained this multiple times:

A: unset foo
B: foo = nil

Because it doesn't do the same thing as unset.

In shell, this leaves foo declared in a local scope:

  local foo # declare
  unset foo # unset

In Python, this doesn't:

  foo = None # declare
  del foo # undeclare

They are *not* functionally the same thing.

Cheers.
