Thanks everyone! And in return, here's an improved version which can
deal with longer entries, like Comodo's:

dig +short -t TYPE257 "$@" | perl -nE '@x = split(); splice(@x, 0, 2);
say map(chr, map { hex } (join("", @x) =~ m/../g ))'

It seems depressingly few domains deploy CAA, having checked a selection
of famous ones. Perhaps we need more publicity for it.
