[web2py] simjsonrpc Client and Keyword Arguments

[Ross Peoples]

I know that the XMLRPC spec doesn't support keyword arguments, but JSONRPC 
does. I have been playing with the new simplejsonrpc client and it doesn't 
seem to support keyword arguments.

Here is an example controller:

@service.jsonrpc
def concat(str1, str2, str3=''):
    """
    Concatenates two strings. Supply a third string if needed.
    """
    return str1 + str2 + str3


And for the client code (from console):

from gluon.contrib.simplejsonrpc import JSONRPCClient
c = JSONRPCClient('http://127.0.0.1:8000/rpc_test/default/call/jsonrpc')
c.concat('hello ', 'world', str3='!!!')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: <lambda>() got an unexpected keyword argument 'str3'

Is it possible that the new simplejsonrpc client could support this?

Thanks
