We (not sure how much help I'll be, but I'm in) need to deal with
Chris A's point that a pure memoizing object doesn't help with the
mutable defaults problem. That is with
def foo(cookiejar=defer ):
foo() produces a late bound empty list that will be used again the
next time foo() is invoked.
Yeah... this is a good point, and it is more frustrating to cover the late-bound argument case. I welcome edits to the proto-PEP (you can add yourself as co-author, even if you wind up at -1 on it :-)).
I think I'm more-or-less U+1F922 on "deferred deferred" myself.
Keeping medicines from the bloodstreams of the sick; food
from the bellies of the hungry; books from the hands of the
uneducated; technology from the underdeveloped; and putting
advocates of freedom in prisons. Intellectual property is
to the 21st century what the slave trade was to the 16th.
