Yes.  However, you cannot use that syntax directly.  You rather use it
by establishing EXCEPTION clauses in BEGIN/END blocks.  Upon entering
any BEGIN/END block which has an EXCEPTION clause, an implicit SAVEPOINT
is executed.  If any exception (read: error) is found while executing
the block, the savepoint will be automatically rolled back and control
passed to the EXCEPTION block.
