Question

This was actually stated in a meeting, by a senior developer. Has anybody ever heard the following?
"The -- uses less space than a blank like, in the compiler"

Answer 1

In case you need proof:
CREATE OR REPLACE PACKAGE space_test_blanks
AS
    v_dummy INT;
END space_test_blanks;
CREATE OR REPLACE PACKAGE space_test_cmmnts
AS
    v_dummy INT;
END space_test_cmmnts;
SELECT *
FROM   user_object_size s
WHERE  s.name LIKE 'SPACE_TEST%';
NAME                        TYPE          SOURCE_SIZE PARSED_SIZE  CODE_SIZE ERROR_SIZE
SPACE_TEST_BLANKS           PACKAGE                75         192        246          0
SPACE_TEST_CMMNTS           PACKAGE               111         192        246          0
