Inspired by others here, I tried hacking something together myself

  from functools import partial
  
  class Pipeable(object):
      def __init__(self, fn):
          self.fn = fn
  
      def __ror__(self, lhs):
          return self.fn(lhs)
  
  def pipeable(fn):
      return lambda *args: Pipeable(partial(fn, *args))
  
  filter = pipeable(filter)
  map = pipeable(map)
  list = pipeable(list)
  sum = pipeable(sum)
  min = pipeable(min)
  max = pipeable(max)
  any = pipeable(any)
  
  # Usage:
  
  range(1, 100) | filter(lambda x: x < 50) | max()
  # 49
  
  [1, 2, 3, 4] | filter(lambda x: x % 2 == 0) | map(lambda x: x * 3) | list()
  # [6, 12]
  
  [1, 2, 3, 4] | map(lambda x: x >= 5) | any()
  # False
