@solid/objects should already have a class defining containers - please migrate to that and remove the custom definition for containers that you are modifying here.

@jeswr I’ve opened a PR on solid/object to fix empty-container resolution in ContainerDataset (so we don’t need to maintain that logic in this repo).
Once that’s merged and published on npm, I’ll update this PR to use @solid/object and remove the local definitions, as requested.
