When you want to abstract on structs "having" a given field (by name) of a given type, I think. Although that may come in Go at some point.

I think Go interfaces are row-polymorphic aren't they? I'm also wondering what the difference between row-polymorphism and ad-hoc polymorphism (a la C++ templates) is.
