Unlike ans, this previously wasn't documented:

help?> ans
search: ans transpose transcode contains expanduser instances MathConstants readlines LinearIndices leading_ones

  ans

  A variable referring to the last computed value, automatically set at the interactive prompt.

help?> err
search: error errormonitor ErrorException @error stderr InterruptException showerror LoadError InitError

Couldn't find err
Perhaps you meant error, zero, repr, eof, eps, esc, exp, end, nor, rm, xor, Ptr, for, try, @error, stderr or merge
  No documentation found.

  Binding err does not exist.

Found while looking at #48299

Is this documented in the Julia documentation? Should it be?

It was originally added in #40642, which also mentioned it in NEWS.md. I think the docstring just got overlooked.
