Changing eval to an interface method would work, but wouldn't get quite the same effect. The way I see it, there's a two-dimensional problem here: one dimension is the different cases for the type (I, B, Add, Mul, Eq), and the oth

You can get a stronger sum type using the visitor pattern (which is the typical way to get sum types in Java). I ported the code in the post to use that approach, and here's what it looks like: http://play.golang.org/p&

One potential downside is that it's a lot harder or more computationally expensive to figure out class/interface relationships in IDEs or other tools. (I haven't used Go, though, so I'm not sure what kinds of tools are available for it.) Ge

Good language-aware syntax highlighters do a lot more than highlight keywords and other syntactic things, and can make code more readable in a nontrivial way. For example, Eclipse's Java editor will color things differently based on the sco
