I was wondering myself, of course. But in Nathann's examples, the arguments to the dictionary variables are any strings, e.g., y["g"]*y["h"] from the original post. Anyway, Nathann, indeed Infinite Polynomial Rings would be a possible approach if you address your variables by natural numbers, x[1]*x [140]+3*y[0]*x[2], rather than by arbitrary strings. They are, of course, described in the Sage References.
