FIXME: I know this probably isn't a good idea, but what's the better solution?
Hack: we want a way to force a NULL return in certain cases (e.g. function delayed). Since no function should ever reasonably return
an error, we use the error type to represent this case.
Note that re-using a type that a function could reasonably return breaks down in the case of e.g. a delayed function, where the function
will have a very specific type but still return NULL because things have not yet been evaluated. Thus, if the delayed method returns a
bool, and our garbage return value is a bool, then how do we know whether or not the Val* returned by the function is actually meaningful
in the general case?
