This is not the case. Quite to the contrary, ZPublisher (its "mapply") cannot
handle "*args" and "**kw" argument definitions.
For some unknown reason, "mapply" seems to get the method signature
wrong and thinks it has to call the object with 4 arguments.
Apparently, your change did not modify what "mapply" sees and
your object now accepts (almost) arbitrary many arguments.
"mapply" is often tricked out by a "func_code" definition.
Maybe, your class has such an attribute and it does not
match the "__call__" signature?
