Comment (by EvilDMP):
There's actually a worse problem with `memoize`, that Shai Berger has
pointed out: it chokes on keyword arguments...
His example:
{{{
>>> from django.utils import functional as F
>>> def f(a,b): return a+b
...
>>> cache = {}
>>> f = F.memoize(f, cache, 2)
>>> f(3,4)
7
>>> f(3,b=4)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: wrapper() got an unexpected keyword argument 'b'
>>>
}}}
