[Python-ideas] Object grabbing

[Pavol Lisy]

I just tried to extrapolate this idea a little bit.

I searched for sources with many "self" in one line and found this
function in mpmath/calculus/extrapolation.py:

    def factor_sidi(self, i):
        return (self.theta + self.n - 1) * (self.theta + self.n - 2) /
self.ctx.mpf((self.theta + 2 * self.n - i - 2) * (self.theta + 2 *
self.n - i - 3))

    def factor_sidi(using self, i):
        return (.theta + .n - 1) * (.theta + .n - 2) /
.ctx.mpf((.theta + 2 * .n - i - 2) * (.theta + 2 * .n - i - 3))

What dou you think?
