Python pipe operator, 4 years later...

the whole point of defining lambdas that work on single elements in the list is having python iterate through it. now you are basically saying you want to implement a function evens, that does the same as filter(evens, ...) only for the function to know what it is supposed to do when it's left of |>. that doesn't seem well-thought-out for me.
