!? It's true that in Python all are references, but there are inmutable
objects in Python, like int, float, strings and tuples. From a practical
POV it exactly the same as value types, if you do:

def f(x, y):
	x = 5
	y = (1, 3)

a = 1
b = (5, 9)
f(a, b)
print a, b

prints "1 (5, 9)", not "5 (1, 3)".

So I can't see how you like Python's way and not D's way.
