Not functions.... lisp-style expressions. With all sorts of lazy evaluation and things that I really can't describe in python terms. If sage can or does support those expressions that would be really useful to Mathematica migrators. > What's the benefit of parsing a string? Aside from the w00t-factor. I am going to guess that maybe half of my lines of Mathematica code contain a /. somewhere. I just opened up a random file and had a look... Found one dodgy line with four of them. Lots of things like: r[res][t] /. results /. t -> tmax I suspect that your post is exactly right. But William wanted to know what we miss from Mathematica. I'm Dave, and I'm really going to miss that w00t factor.
