Why must ctor args be a dict or list?

[bboerner]

This:

class datetime(object):
    def __init__(self, args):
        self.args = args

    def __str__(self):
        return self.args

jsonrpclib.config.classes.add(datetime)

x = { "__jsonclass__": ["datetime", "2013-01-10T22:22:20"] }
result = jsonclass.load(x)
print "x: %s, result: %s" % (x, result)

returns:

# Traceback (most recent call last):
#   File ".\test.py", line 59, in <module>
#     result = jsonclass.load(x)
#   File "c:\Python27\lib\site-packages\jsonrpclib\jsonclass.py", line 140, in load
#     raise TranslationError('Constructor args must be a dict or list.')
# jsonrpclib.jsonclass.TranslationError: Constructor args must be a dict or list.

Why not this?
