My point was that I was making fun of CS professors that demand a comment on
every line of code, regardless of how clear the line of code is. The fact that
I happened to use 'x' as a variable name was inconsequential, and I felt that
Chris's criticism of using a single-letter variable name was pedantic because
it missed the point entirely and picked on something else that wasn't an issue.
I was trying to illustrate the point that some professors would demand you
write code like this...
# increment the line count
lineCount += 1
# Check if line count is over 10
if lineCount > 10
# Tell the user there are too many lines
print 'There are too many lines!
...which is obviously bad commenting style. But I guess my original minimal
example was too minimal.

I use Google Groups which seems to be pretty unpopular on this list. Does it
break thread organization? Or is it really just a politeness thing?
