Sets

Sets are useful for iterating over objects during IaC provisioning to create unique resources. When using sets a unique identifier is required by tools like Terraform, but those IDs can be difficult to autogenerate in a safe, declarative manner.

When using sets patternProperties can be useful for controlling the keys in maps to be used as a unique ID during provisioning.

In the example below a user would be prompted to enter a unique identifier for each car added.
