Almost. While it moves the ugliness, at least it allows separating the
iteration logic from the handling logic, which is already a big step ahead!

That said, there is:

  with <expression> as <name>:
      ...

so why not:

  while <expression> as <name>:
      ...

and also:

  if <expression> as <name>:
      ...


Thanks to everybody for their input!
