Py3K idea: why not drop the colon?

I use four-space indents whenever possible.  If I have a multi-line
condition I find that the condition indents to the same level as the the
indented block, e.g.:

    # Oh, wait, I shouldn't have typed that colon just now!  It's not
    # necessary.  Oh, darn.  Hmmm... What does Strunk say?
    if (some_long_expression and
        some_other_long_expression and
        yet_another_long_expression):
        that_was_a_long_expression = True

I don't know if this is just a shortcoming of the style I use to break lines
in a long expression or what, but the colon makes it clear where the
condition ends and the indented block begins.
