Sorry, missed that!  I don't generally notice signatures much, partly 
because Thunderbird is smart enough to "grey them out" (the main text is 
displayed as black, quoted material in blue, and signatures in a light 
gray.)

I don't have a firm answer (though I suspect the language reference 
does) about when "dedicated" parentheses are required around a generator 
expression.  I just know that, so far, they just work when I want them 
to.  Like most of Python. :-)
