Cannot handle unhashable types in function arguments #36
Description
plone.memoize.view.memoize cannot handle function arguments which are unhashable types.
E.g.:
When adding this example to view.rst:
$ git diff

J.D.: goodbye cruel world! raise--roofbeams
+ >>> print(msg.getMsg('J.D.', lower=['shields', 'engines']))

We can alter data underneath, but nothing changes::
>>> msg.txt1 = 'sound and fury'
