-=item * Subroutine calls provide lvalue context to arguments
-
-Beginning with version 5.002, all subroutine arguments are consistently
-given a "value may be modified" context, since all subroutines are able
-to modify their arguments by explicitly referring to C<$_[0]> etc.
-This means that any array and hash elements provided as arguments
-will B<always be created> if they did not exist at the time
-the subroutine is called.  (perl5 versions before 5.002 used to provide
-lvalue context for the second and subsequent arguments, and perl4 did
-not provide lvalue context to subroutine arguments at all--even though
-arguments were supposedly modifiable in perl4).
