it's not as safe as you think - that's not true. in some ways, go's interfaces are more general than haskell's type classes. the two are pretty much orthogonal to one another, in fact. go's interfaces are more equivalent to haskell's Type.Dynamic except less restrictive (fromDynamic asserts a particular type, which is like asserting a static type in go rather than an interface type). haskell's type classes work top down - one type identifier always represents the same underlying type; whereas in go each variable of interface type can hold a different underlying type.
