And is it really a problem if we delay the late-binding to the point
where the value is actually needed? Here's a toy example:

def function(spam, eggs=None, cheese=None):
if eggs is None:
eggs = cheap_default()
# do stuff using eggs

if condition:
return result
if cheese is None:
cheese = expensive_default()

-1. Too confusing. Consider
def function(a, ct=>len(a)):
if random.randint(0,1):
a.append(42)
for i in range(ct):
# presumably ct may or may not be 1 more than the original
length of a
Best wishes
