Yes, the fact that so many newbies complain about it is very significant.
Perhaps we need to do a better job of presenting the concept. For example,
instead of tossing it out there and then defending against complaints
perhaps it would be better to take the offensive: first make a case for
why the "normal" way to delimit blocks has its drawbacks, and then present
the Python way as a solution to a problem.
But just because people consistently complain about something does not
mean the answer is to bow to their wishes. From an arrogant point of view,
they're newbies, so what do they know? ;-) Seriously though, I enjoy
Python because it _is_ different - and I usually derive benefit from the
ways in which it is different (i.e. - it's not different for arbitrary or
random reasons). It's significant that lots of newbies complain about "no
curly braces", but it's as least as significant that once people use it
for awhile they tend to end up liking it.

Well, as you know you can always do an "# end" comment which really gives
much of the same benefit. At the bottom of my Emacs window it tells me
which block I'm closing (e.g. "Closes block: ...try:"), other editors
probably do the same. Also, it seems like whenever it's not readily
apparent which block I'm in, then the _real_ problem is sloppy code on my
