While we're still on the subject of Python and Guido Von Rossum's blog 
entry, I noted the following:

"but for me the high point of the evening was Miguel de Icaza's 
excitement over Python's feature which makes text files iterators 
yielding the lines of the file in succession, so that you can write

for line in open(filename):
       ...process line... "

At which point I sighed.
