/* This file defines an internal function for processing default arguments
with proxy classes.
There seems to be no straightforward way to write proxy functions
involving default arguments. For example :
def foo(arg1,arg2,*args):
proxyc.foo(arg1,arg2,args)
This fails because args is now a tuple and SWIG doesn't know what to
do with it.
This file allows a different approach :
def foo(arg1,arg2,*args):
proxyc.__call_defarg(proxyc.foo,(arg1,arg2,)+args)
Basically, we form a new tuple from the object, call this special
__call_defarg method and it passes control to the real wrapper function.
An ugly hack, but it works.
