As it turns out, Python has similar ways of decomposing data structures:

(x, y) = foo or def bar((x, y)): # etc. and I have sometimes wished I could write z as (x, y) = foo or def bar(z as (x, y)): # etc. However, it's not real high on my list of priorities, and I suspect that many Pythonists consider these usages to be a frill anyway.

For the assignment case, you can do this:

foo = (1,2) (x,y) = z = foo x 1 y 2 z (1, 2)

Function arguments are not covered by this trick, but

def bar(z):
    (x,y) = z

probably isn't too much overhead...

(Or did I miss your point?)
