I would consider this to be bad style:
>qq{
...
}<; # yuck!
This is what I'd consider good style:
my @output =
map { $_->[0] }
sort { $a->[1] cmp $b->[1] }
map { [>$_<, expensive_func($_)] } # print original lines
<>;
(Modified from <http://www.perlmonks.org/index.pl?node_id=9108>)
The main point of this statement is the Schwartzian Transform, but it
also prints the original lines en passant.

Agreed. Good style would avoid this problem. The example in the
synopsis of this RFC should be:
my $output = >"Print this line.\n"<;
