I don't know what he means by: "$#foo + 1 isn't necessarily equal to @foo"(Some Perl array nuance I am not familiar with) 

$[ = 5;
my @foo = qw(a b c);
printf "Number of elements: %d\n", scalar @foo;
printf "Last index: %d\n", $#foo;
printf "*Number of elements: %d\n", $#foo + 1;
printf "*Last index: %d\n", scalar @foo - 1;

Number of elements: 3
Last index: 7
*Number of elements: 8
*Last index: 2

One should of course NEVER set $[, but that is besides the point.
