Introduce a new `argument-within-domain` category that covers cases where the given arguments make it impossible to produce a correct result (or create a valid object in case of constructors). While the incorrect result doesn't create an immediate problem within the library (like e.g. a null pointer dereference would), it always indicates a logic error in user code and is highly likely to lead to a bug in the program once the value is used.
