in thread I am confused by a "Learning Perl" sample showing "unshift"

Therefore:
unshift @a, @b same* as  push @b, @a

*But see clarification from choroba:

    :-)

    No, as the first one changes @a, but the second one changes @b. The result is the same, but ends up in a different container.

    map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    Yes good point! :)

    ( provided choroba's comment, that the targets are swapped. )
