That looks like a good reference. I was thinking of the remark in Ian Connell;s (free online) lecture notes on elliptic curves, available from http://www.math.mcgill.ca/connell/public/ECH1/, where he says (bottom of first page of Chapter 2) The pitfall to avoid here is that the isomorphic rings

Even before getting to Laurent series, multivariate power series are harder to define than you might think, so I would avoid implementing them at this point unless you have a specific need for them! You need to be really careful since K[[x]][[y]], K[[y]][[x]] and K[[x,y]] are not all the same. T

I think you want the multivariate Laurent series to form a field. For x + y to have an inverse, you should additionally make a choice of an ordering x < y or y < x to decide what its series expansion looks like. The best definition might therefore be the iterated Laurent series, as described in Ch
