Not quite, what I had in mind would be this one-liner:

a, b = [b, *[a = [a, b]]]

I have a slight completely unfounded doubt the interpreter would  
implicitly associate (a = a) in the middle of the expression.

The results observed in irb ARE however ambiguous with respect to both of  
those possible interpretations.
