BackedEnum pseudointerface manual page: The BackedEnum interface

Note that this (pseudo)interface cannot actually be implemented as a standard class; it can only be (pseudo)implemented by declaring a backed enum.
Definition
interface BackedEnum extends UnitEnum {
static function from(int|string $value): static;
static function tryFrom(int|string $value): ?static;
string|int $value; // pseudocode
// INHERITED from UnitEnum (unmodified):
static function cases(): array;
string $name; // pseudocode
}
The member-variables are labelled "pseudocode" because a normal interface can't declare member-variables.
