Never say never. You're correct for pure reading like so:
$x = @a[0];
But for less pure forms of reading:
foo(@a[0]);
auto-vivification will have to happen in some cases. e.g. if foo
requires a lvalue parameter. You can't know if an actual write will
happen, so you have to auto-vivify in order to pass a reference.
Or did I miss something there?
