PL SQL Find all objects in other objects

I wrote some code that allows you to find exactly where all references in scripts (sprocs, views) your objects are. This includes tables, views, indexes, sequences. Run it, and let me know what you think!

WITH OBJECT_OWNERS
AS (
 SELECT 'SYS' AS OBJECT_OWNER
 FROM DUAL
 )
SELECT OBJECT_OWNER,
 OBJECT_TYPE,
 OBJECT_NAME,
 REFERENCED_IN_OWNER,
 REFERENCED_IN_OBJECT_TYPE,
 REFERENCED_IN_OBJECT,
 REFERENCED_IN_LINE,
 REFERENCED_IN_TEXT
FROM (
 SELECT OBJECT_TYPE,
 OBJECT_NAME,
 OWNER AS OBJECT_OWNER
 FROM ALL_OBJECTS
 WHERE OWNER IN (
 SELECT OBJECT_OWNER
 FROM OBJECT_OWNERS
 ) MINUS
 SELECT 'TABLE' AS OBJECT_TYPE,
 OBJECT_NAME,
 OWNER AS OBJECT_OWNER
 FROM ALL_OBJECTS
 WHERE OWNER IN (
 SELECT OBJECT_OWNER
 FROM OBJECT_OWNERS
 )
 AND OBJECT_TYPE = 'MATERIALIZED VIEW'
 ) QUALIFIER
LEFT JOIN (
 SELECT OWNER AS REFERENCED_IN_OWNER,
 TYPE AS REFERENCED_IN_OBJECT_TYPE,
 NAME AS REFERENCED_IN_OBJECT,
 LINE AS REFERENCED_IN_LINE,
 TEXT AS REFERENCED_IN_TEXT
 FROM ALL_SOURCE
 WHERE TEXT NOT LIKE '--%'
 ) DETAILS
 ON INSTR(DETAILS.REFERENCED_IN_TEXT, QUALIFIER.OBJECT_NAME) != 0
ORDER BY OBJECT_OWNER,
 OBJECT_TYPE,
 OBJECT_NAME,
 REFERENCED_IN_OWNER,
 REFERENCED_IN_OBJECT_TYPE,
 REFERENCED_IN_OBJECT,
 REFERENCED_IN_LINE
