In particular, this was found to happen in #5099 because a `Result` projection node was not deduplicating across two separate `isplit`s that created it. (This is a separate issue we should also fix; `needs_dedup` is I think overly conservative because `Result` can project out a single value from a pure or impure node, but the projection itself should be treated like any other pure operator.) In any case, if we have a value `v0` and two separate `Result { value: v0, result: N, ty }` nodes, each of these will fill in the type `ty` for the `N`th output of `v0`, and the second will idempotently overwrite the first; we should loosen the assert so that it allows this case. Fixes #5099. Fixes #5100.
