New submission from Marek Otahal:
I'd like to use @lru_cache in a library. The problem is I can't know the
optimal values for 'maxsize', I need to set them at runtime.
I came with 2 possibilities:

Hope this example is not too confusing, it's a patch to my code and lru_cache

It implements both approaches as highlighted above, and in the test both of
them are used (that does not make much sense, normally one would

Hi David,
> How is (1) different from:
@lru_cache(maxsize=1000)
def foo_long(self, arg1...)
As I mentioned, for use in a library that is called by end-users. They can call
functions and modify params, but do not edit the code. It's up to me (lib d

or for (2):
class MyLib():
def __init__(arg1, arg2):
self._cacheSize = someComputation(arg1, arg2) # returns a number
@lru_cache
def foo_long(self, arg1, **k
