I'd like to suggest we copy C#'s idea of verbatim identifiers, but using
a backslash rather than @ sign:

    \name

​Personally, I prefer $name as originally suggested in that thread. It has the advantage of precedence from other languages as a variable indicator (even as far back as BASIC for me) and is more visible (which IMO is a positive, but others may see as a negative).​

​In either case​, I'm +1 for some way of indicating a verbatiim identifier.

But I think this doesn't look too bad:

​​
    of = 'output.txt'
    \if = 'input.txt'
    with open(\if, 'r'):
        with open(of, 'w'):
            of.write(\if.read())

​​
    of = 'output.txt'
    $if = 'input.txt'
    with open($if, 'r'):
        with open(of, 'w'):
            of.write($if.read())
maybe even nicer than if_.

Some examples:

    result = \except + 1

​result = $except + 1​
 
    result = something.\except

​result = somthing.$except​

    result = \except.\finally

​result = $except.$finally

@\return
def func():
    pass

@$return
def func():
    pass
