 Undefined constants are not defined implicitly -- forward usages of constants are also classified as undefined constants here. A distinction between class/interface constants and top level constants is made.

Moreover, a notice is emitted stating that the corresponding constant was undefined. For qualified usages, an exception of type [`Error`](14-classes.md#class-error) is thrown.
