is it possible to remove the ':' symbol in the end of lines starting with 'if', 'while' etc?

[openopt at ukr.net]

I don't know to which forum should I post the message
I hope someone related to the Python kernel development will read &
consider the idea
I'm (a former? meanwhile not sure) MATLAB user & it's very annoing
typing each time for example
while i:
     print i
     ...
instead of
while i
    print i
    ...
of course if all is written in a single line ':' I guess should not be
omited

Thank you for you suggestions.
Sorry my bad English.
