Assuming you can read the one, the other is at least as
readable.

In my post I was attempting to point out that I find list 
comprehensions less readable than the equivalent, longer but 
more explicit while loop version, not that one list comprehension 
is more or less cryptic than another.

(I'm quite sure in time list comprehensions will be quite
readable to me.  Eventually even Perl can become readable
to someone.  That doesn't mean the meaning of either is
obvious to a newcomer, which is what bothers me about both.)
