".>>>" is a good idea! (OT, was: Re: do you master list comprehensions?)

This is the first time I see that and I totally like the idea of writing 
".>>>" instead of ">>>" at the beginning of a line. Thank you Dr. Dobb! 
It's unfortunate for c.l.py that Python uses ">>>" as the default prompt 
as it messes up the display on mail/news readers that provide "syntax 
highlighting" for quotes.

I wish everyone would write examples that way! On the other hand - three 
levels of quoting are really rare, maybe it would be easier to change that 
in the mail readers...

... or in Py3k ?

Stefan
