My intuition is no, it's not important enough to alter the syntax, despite
being an important task.

If you'd like to give it a shot, try to find something which is currently
invalid syntax, but does not break compatibility. The latter criteria means
no new keywords. The syntax should look nice as a single line with
reasonably verbose variable names.
One issue is that Python code is mostly 1-dimensional, characters in a
line, and you're trying to express something which is 2-dimensional, in a
sense. There's only so much you can do without newlines and indentation.
