I agree completely.  And as a recent convert to Python, I have to say
that I *like* the colons.  I found the whitespace-and-colon thing
really irritating... for about 2 hours.

The colon makes it easier to eyeball where a block statement begins in
the absence of braces around the block, it allows one-line if
statements (which I use a lot), and it means that even the stupidest,
simplest editor can figure out where auto-indentation is needed, namely
following any line that ends with a colon (except in a triple-quoted, I
guess).

Contrast that with Perl, where in years of professional and hobby use I
have not found a single editor that gets indentation right more than
about 90% of the time.  The syntax is too darn complicated.  With
Python, figuring out where to auto-indent is trivial.  Works for me.
