Running the following code shows "2 1 4 3", but in reference manual
http://docs.python.org/reference/expressions.html#expression-lists
the evaluation order described as
{expr1: expr2, expr3: expr4}

def f(i):
    print i
    return i

{f(1):f(2), f(3):f(4)}

I found some of past discussions about this problem, for example,
http://mail.python.org/pipermail/python-dev/2002-November/030461.html

http://svn.python.org/view?view=rev&revision=30148
, but current implementation seems not to reflect these accomplishment.

In present, which behaviour is legal?
