Abstract
A repository of key-value data may store a first object value having an internal structure of a hierarchy of sub-objects. The repository may receive a request to modify the first object, expressed as a function, without side effects, of one or more parameters. Values may be assigned to the one or more parameters by mapping from the parameters to locations in the hierarchy of sub-objects. A second object may be formed based on the return value of the function. The first object may be replaced in the repository by the second object.
