Generalized folds for system of algebraic data types
Illustration
A data model for companies of the @system requires a system of algebraic data types such as follows:
Thus, a generalized fold for companies also needs to be parameterized in multiple types: one for each type in the system:
We can set up some interesting baseline behavior on companies. The following algebra models deep identity over companies such that the company structure is fully traversed and rebuilt:
An operation for cutting salaries in half can now be derived from mapCompany simply by record update such that the case for employees realizes salary cut:
