Pass parameters to a service handler in rospy

edit

In rospy, message callbacks can have additional parameters, which allows me to write only one callback for different subscribers. For example:

def my_callback(msg, name):
    rp.logwarn(name + "has received the message: " + msg)

subscribers = [
    rp.Subscriber(
        name+'/my_topic',
        MyMessageType,
        my_callback,
        callback_args=name)
    for name in "Alice Bob Carl David".split()]

works perfectly fine. However, the same is not possible for service handlers. For example:

def my_hanlder(request, name):
    rp.logwarn(name + "has received the request: " + request)

providers = [
    rp.Service(
        name+'my_service',
        MyServiceType,
        my_handler,
        handler_args=name)
    for name in "Alice Bob Carl David".split()]

raises an error, because handler_args is not a parameter of the constructor rp.Subscriber.

How can I pass additional parameters to a service handler?
