Maybe that's common to python devs, but I would expect else to be
executed if the iterator yielded nothing/was empty.
IMO if you break you'll already be in a conditional of some sort in the
for body, so you can add more code there. But the else-on-empty would
save you the trouble of wrapping the whole for block e.g.:
if not empty { for { ... } } else { ... }
