Oracle Database Discussions

So, Oracle maintains dynamic performance tables. Views are created off of them, and then public synonyms are created off of those views and they begin with V$. Very good. But something doesn't make sense to me.

V$DATAFILE is a synonym that references a view named V_$DATAFILE:
SQL> select dbms_metadata.get_ddl('SYNONYM', 'V$DATAFILE', 'PUBLIC') from dual;

DBMS_METADATA.GET_DDL('SYNONYM','V$DATAFILE','PUBLIC')
--------------------------------------------------------------------------------

CREATE OR REPLACE PUBLIC SYNONYM "V$DATAFILE" FOR "SYS"."V_$DATAFILE"

SQL> select object_type from dba_objects where object_name='V_$DATAFILE';

OBJECT_TYPE
-------------------
VIEW

But the definition of the view references the.... synonym itself?
SQL> select dbms_metadata.get_ddl('VIEW', 'V_$DATAFILE', 'SYS') from dual;

DBMS_METADATA.GET_DDL('VIEW','V_$DATAFILE','SYS')
--------------------------------------------------------------------------------

CREATE OR REPLACE FORCE VIEW "SYS"."V_$DATAFILE" ("FILE#", "CREATION_CHANGE#",
"CREATION_TIME", "TS#", "RFILE#", "STATUS", "ENABLED", "CHECKPOINT_CHANGE#", "C
HECKPOINT_TIME", "UNRECOVERABLE_CHANGE#", "UNRECOVERABLE_TIME", "LAST_CHANGE#",
"LAST_TIME", "OFFLINE_CHANGE#", "ONLINE_CHANGE#", "ONLINE_TIME", "BYTES", "BLOCK

ME", "FIRST_NONLOGGED_SCN", "FIRST_NONLOGGED_TIME", "FOREIGN_DBID", "FOREIGN_CRE
ATION_CHANGE#", "FOREIGN_CREATION_TIME", "PLUGGED_READONLY", "PLUGIN_CHANGE#", "
PLUGIN_RESETLOGS_CHANGE#", "PLUGIN_RESETLOGS_TIME") AS
select "FILE#","CREATION_CHANGE#","CREATION_TIME","TS#","RFILE#","STATUS","ENA

OREIGN_CREATION_CHANGE#","FOREIGN_CREATION_TIME","PLUGGED_READONLY","PLUGIN_CHAN
GE#","PLUGIN_RESETLOGS_CHANGE#","PLUGIN_RESETLOGS_TIME" from v$datafile

So the view definition references a synonym, and the synonym references the same view... seems circular. Is this Oracle Corp's way of telling me to bugger off? I just wanted to look up the name of the dynamic performance table out of curiosity.
