 * Used to represent a value that will either be escaped to a literal, or a bind parameter.

 * without mapping to a column name or any other transformation.
 *
 * This method supports strings, table structures, model classes (in which case the identifiers will be the model schema & table name), and model definitions (same behavior as model classes)
 *
 * @param values The identifiers to escape. Automatically joins them with a period (`.`).
 * @example
 * ```ts
 * sequelize.query(sql`SELECT * FROM users WHERE ${identifier('firstName')} = 'John'`);
 * ```
 *
 * Will generate (identifier quoting depending on the dialect):
 *
 * ```sql
 * SELECT * FROM users WHERE "firstName" = 'John'
 * ```
