It was less the overall readability I was commenting on, and more the
claim that the listcomp required a 'back-and-forth' parsing to
understand. As you've reinforced, the listcomp can be readily
converted back to the multiple-line form by the inclusion of colons &
EOL markers, which means you can make as much sequential sense from a
listcomp as you can a for-loop.
