Am I right in thinking the key issue here is that => is *not* used for
"items"? So
def frob(n=>len(items), items=[]):
print(n)
items.append(1)
gets very complicated to reason about. What does this print?
frob()
frob()
frob(items=[1,2,3,4,5])
frob(3, [])
frob()
frob(3)
frob()
Even if someone *can* provide an answer, I'd be reluctant to accept
that any answer could be described as "intuitive". And "well, don't do
that" is just ducking the question - in essentially the same way as
"it's implementation defined" does...
