Anything that allows for interpolated context (which means qq, qx and qr) can fairly easily be adapted to use here docs:

    print `${\<<HERE}`;
        date
    HERE
[download]

or

    print qx {${\<<HERE}};
        date
    HERE
[download]

And for qx:

    print qr /${\<<HERE}/;
        x*foo
    HERE
[download]

For q and qq, we already know what to do, single or double quote the delimeter. Which leaves us with qw, which is fairly simple too:

    my @words = split ' ' => <<'HERE';
       some words go here
    HERE
