Good point. If one does fib(10000) and wants to dump the cache without
dumping all references to the function object, one can currently do
fib_iter.__kwdefaults__['_cache'] = [0,1]
to truly reset the cache, at least with CPython.
Alternatively:
new_cache = [0, 1]
fib_iter(100, new_cache)
fib_iter(200, new_cache)
No, that is not an alternative to what I wrote ;-).
As Stefan pointed out above, passing a value to over-ride a default only
substitutes for the default in that one call. It is like a temporary
substitute teacher. It does not replace the default in the function
object. The assignment I give above is like a permanent replacement
teacher. The previous cache list will be garbage collected.
