in reply to Autovivification of scalars in sub calls

Um, qw( @$x ) is not a "builtin function". It's the single quoted string '@$x'.

    True, although an example with print demonstrates the behavior to which tlm was referring: 

    perl -Mstrict -le 'my $x; print @$x'
Can't use an undefined value as an ARRAY reference at -e line 1.

perl -Mstrict -le 'my $x; sub { }->( @$x ); print @$x'
