F.2.12 library(error)
| current_type/3 | True when Type is a currently defined type and Var satisfies Type of the body term Body succeeds. | 
| domain_error/2 | The argument is of the proper type, but has a value that is outside the supported values. | 
| existence_error/2 | Term is of the correct type and correct domain, but there is no existing (external) resource that is represented by it. | 
| has_type/2 | True if Term satisfies Type. | 
| instantiation_error/1 | An argument is under-instantiated. | 
| is_of_type/2 | True if Term satisfies Type. | 
| must_be/2 | True if Term satisfies the type constraints for Type. | 
| permission_error/3 | It is not allowed to perform Action on the object Term that is of the given Type. | 
| representation_error/1 | A representation error indicates a limitation of the implementation. | 
| resource_error/1 | A goal cannot be completed due to lack of resources. | 
| syntax_error/1 | A text has invalid syntax. | 
| type_error/2 | Tell the user that Term is not of the expected Type. | 
| uninstantiation_error/1 | An argument is over-instantiated. |
