> Autogenerated bindings for Clownfish subroutines which accept or return
> clownfish Obj should be mapped to Go's "empty interface" type, `interface{}`.
> This sacrifices some type safety, but it is the only way to achieve certain
> desirable effects.  For example, it should be possible for Vector's Push()
> method to take a Go string, instead of requiring the user to perform a manual
> conversion to a Clownfish object.  Similarly, Vector's Pop() should be able to
> return a Go string.
> Functions which need to return an actual clownfish Obj wrapped in a Go struct
> will need to have hand-coded bindings, but there are fewer of those so
> converting Obj by default is the better choice.
