It is handy, sometimes.
But I do think that the overhead of creating a longish string every time
you print something, which is then simply discarded, is not really

I think what I really want is a tee operator.
The problem with what you have there is that it hides the act of
output within an arbitrarily long circumfix operator whose terminating
portion is potentially very far
This is what I'd consider good style:
my @output =
map { $_-[0] }
sort { $a-[1] cmp $b-[1] }
map { [$_, expensive_func($_)] } # print original lines
;

The main point of this statement is the Schwartzian

I'd prefer a different name (tee?) and keep print as it is.
Pretty much all the stuff being discussed right now can be stuck in a
module:
package Print::Variations;
use Exporter;
@EXPORT =
Perl supplies an operator for line input - angle brackets. This is no
analogous operator for output. I propose "inverse angle brackets":
"Print this line.\n";
