Does indentation matter, and are you proposing blocks of
"real" code in there?  I suspect that writing it this way
is going to tempt people to include more code, maybe expect
to be able to write "else" clauses, put in "break", etc.

I think if you do it this way, the above is so close to how
you'd write it without list comprehensions that it largely
eliminates the succinctness that motivated list comprehensions
in the first place.
