because the arguments passed to the print xsub are not copied.
unlike a perl sub:
sub print {
my(@args) = @_;
}
where @_ is copied into @args.
so there's no advantage for the xsub to accept a scalar ref.
suggestion is to keep refs in perl land, but dereference before passing to
xsub land, like so:
my $html = <<EOF;
...
EOF
output($r, \$html);
sub output {
my($r, $data) = @_;
$r->print($$data);
}
