** tests/extends_fixtures/unified.lime -- v0.4.1 diamond top.
** Extends BOTH oracle.lime and mysql.lime.  Both transitively
** %extends ansi_sql.lime; the diamond converges on ansi's rules.
**
** Diamond resolution per docs/EXTENDS.md:
**   - select_clause: oracle overrode, mysql did not -> oracle wins (Rule 5)
**   - where_clause:  mysql overrode, oracle did not -> mysql wins (Rule 5)
**   - oracle's CONNECT_BY rule + mysql's LIMIT rule both present
**   - ansi's "where_clause ::= ." (empty) preserved on both arms
**     -> dedup
