I started with something like that when I was missing function composition in Python. Eventually I ended up with a library [1] including a bunch of other stuff for getting rid of some of the duct tape code you usually need when you just want to compose some functions.

  from pipetools import pipe, X, foreach

  really_angry = pipe | upper | exclaim | exclaim

or...

  really_angry = X.upper() | "{0}!" | "{0}!"


  (1, 2, 3, 4) > foreach((X + 1) | (X * 3)) | max 

You can write some pretty neat looking concise code with this, but also may regret it later when it comes to debugging, especially when lazy evaluation is involved (which is usually the case). The stacktraces tend to be not so helpful...
