[Python-projects] nice-to-have: analyze (some) strings for variable use

[skip at pobox.com]

In this function pylint complains that a and b are unused:

    def f(a):
        b = "some var"
        return "%(a)s, %(b)s" % locals()

It would be nice if it noticed literal % locals() structure and treated
variable references within the string as actual usage.

Thx,
