Yes, we don't have any machinery in the language semantics for declaring something as nondeterministic (easy to solve) or defining the semantics of how it should behave if thus annotated (much harder).
For example, if f() and g() are non-deterministic functions, how do we say in the spec that in the expression (f(), g()), f should be executed before g?
