Problem

Config files ideally do not copy any structure if they only want to set a single key.

Constraints

• strongly hierarchically structured data must still be supported

Assumptions

Considered Alternatives

• data structure is always complete
• to not allow "directory values" or "directory metadata"

Decision

• support holes in KeySet
• See hierarchy example for how to implement a hierarchy that gets rid of the problem that holes might create when iterating over KeySet.
