I don't think he's talking about slicing, I think he's talking about the
type-system hole. It's not unreasonable to assume when reading/debugging code that
any members of a Foo[] will be of type Foo or, if not, that a cast will have been
required somewhere to indicate that fishy things are afoot (afin?). This
conversion subverts that.

@OP: I raised this about a year ago and nobody seemed bothered then; I don't
imagine that's changed.
