You missed the point.  We know why it does not work.  Someone was just
hoping to find a way to use q// and qq// with it.

No way.  Here docs rule, and are much easier to use with printf() and other
functions/operators.

printf(<<EOT, $_, $tracka, $artist, $track, $note, $album, $year);
Track %2s:%.26s:0:%.30s:%.30s:%.30s:%.30s:%.4s:
EOT

print $x == 1 ? <<EOT1 : <<EOT2;
This is cool.
EOT1
This is dumb.
EOT2

Here docs rule.  That simple.  Sure, the simple "$x = <<EOT" can be done
simply with regular quoting.  But to deprecate something this cool and
relatively harmless is Bad.
