Could someone give an example of the second point here? The other two
are concrete and therefore easier to understand and implement. The "take
care" and "can hide" parts of the second make me less certain that I
know what to look for.

Searching the archives for "circular and closure" gives no hits. Is
there a way to point Google at the list?

Just curious--any idea why that might be?

I would've guessed the asymmetry might arise from some lingering
glitches in win32 Perl or Gtk.
