It dawned on me that you could use this idea to make the whole filter/lambda experience vastly more pleasant. I whipped up a quick implementation:
>>> from placeholder import _ >>> numbers = [5, 9, 56, 34, 1, 24, 37, 89] >>> filter(_ < 30, numbers) [5, 9, 1, 24] >>> map(_ + 10, numbers) [15, 19, 66, 44, 11, 34, 47, 99] >>>
Look ma, no lambdas!
I bet someone has already done this before, right?
I thought about it, but couldn't convince myself that it would work properly in all cases. I was thinking in terms of operator overloading of everything possible - how did you do it? Paul.
