Isn't it equally easy to write:

    def foo(x):
        ...

    items = [foo(x) for x in items]


I don't understand the desire to write this as a loop over a 
``items.pop(slice(None))``. You can simply use the same loop body, 
replacing the ``for x in items:`` with ``def blah(x):`` and 
``items.append(y)`` with ``return y``. Low typing effort.
