so we could do

x = (def (a): a)assert x('b') == None

and

x = lambda a: aassert x('b') == 'b'

and about your “misleading constructions”: the ability to put arguments of
function definitions on their own lines is already ugly.

we basically have no switch statement because it would be indented twice or
half, but we indent twice or half when defining functions all the time. and
if your default argument is a function, you’ll definitely want it to be a
simple one anyway or would use the tried

def a(f=None):
    if default is None:
        def f():
