I stand corrected. I had thought the trampoline ("bound method object")

Assuming that bound methods are immutable, this is an implementation detail, either way. However, it is common for a specific method to be called just once on a specific instance. If you have a mixed-case string Ss and want the lowercase version, ss = Ss.lower(), you keep ss around as long as needed. If the bound method is needed repeatedly, you can keep *that* around too.

stack = []
spush = stack.append
spop = stack.pop

for item in it:
  spush(item)
while stack and condition:
  p = process(spop)
