OIDs currently contain a value of type int. The integers are assigned in sequence for the life of the persistent data created by an application based on the framework. Only 2,147,483,647 OIDs can be created.

Structured Combinators

The method currently used to build a structured combinator assumes that all nodes in the resulting tree will contain the same functor (either max or  min). As a result, the tree that is built is "left-handed", i.e. only the the left node of a pair can be non-leaf. This structure is adequate, given the stated assuption, but clearly the ability to create a richer tree structure, with the possibility of mixing multiple functors, would be desirable.
