You mean what my proposal would bring
technically better than e.g.:

for i,e in enumerate(Seq)

Well, nothing, and I will simply use it,
with only difference it could be:

for i,e over enumerate(Seq)

In this case only space holes will be
smoothed out, so pure optical fix.

As for my comment about indexing
preference- something inside me would push me to
write something like:

for i index Seq:
   e = Seq[i]

One could call the second line 'noise', but I can't
explain why, it helps me to read, and I am
not biased to C style or anything.
Also it probably has to do with
variables names, and here I see it
on the second line, note that it is not
always 'e' and they often make sense,
e.g. 'files', 'dirs'.
