[docs] [issue22180] operator.setitem example no longer works in Python 3 due to lazy map

[R. David Murray]

R. David Murray added the comment:

Heh.  There was a discussion in issue 22106 about valid examples for using 'pass'.  This case is analogous to the one I came up with.

  for x in map(...):
     pass

that avoids building a list.

Not that any of it is idiomatic, as you say.
