The most common place I wish for an atomic "test and assign" is with 
regexes, as in your examples.  This would be so much nicer than what we 
have to do now:

    if re.match(string) as m:
        print m.group(0)

The analogy to

    except SomeError as ex:

is very clear.  They are both "Perform some action, capture the result, 
do some test on it, and then make that captured value available bound to 
a name".
