Is there any advantage to using an array over a string here?

I guess it depends on how the variable is used afterwards - if there are additional values being pushed onto the array, it might make sense. It's just assigning a single value to the array; personally I would have written my @sqltt = (<<EOF); to make it explicit that yes, I meant to assign a single value to this array. But if the code then goes on to use $sqltt[0] everywhere, and especially if it doesn't add elements to the array, then it would definitely have been better to just use a plain scalar in the first place.

use warnings;
use strict;
use Data::Dump;

my @sqltt = <<EOF;
Hello,
World!
EOF
dd @sqltt;

__END__
"Hello,\nWorld!\n"

Minor update to wording.
