How about yet another decorator?

def deprecated(f):
    def new_f(*args, **kwds):
        print "warning: deprecated function", f.func_name
        return f(*args, **kwds)
    new_f.func_name = f.func_name
    return new_f

@deprecated
def lepard(a, *args, **kwargs): 
    print a, args, kwargs

>>> lepard(1,2,3, four=4)
warning: deprecated function lepard
1 (2, 3) {'four': 4}
