I think these CAN be useful ... for decorative purposes ...

$arg1 = "arg1";
$arg2 = "arg2";
$arg3 = "arg3";
 
sub f1 { return "1"; }
sub f2 { return "0"; }
sub f3 { return "3"; }

print "${\-+- f1( $arg1 )}";
print "${\+-+ f2( $arg2 )}";
print "${\-+- f3( $arg3 )}";
print "\n"

isn't that far better than the undecorated print statements? ( Same f1(), f2(), f3(), $arg1, $arg2, $arg3. )

print f1( $arg1 );
print f2( $arg2 );
print f3( $arg3 );

And FAR superior to the boring and mundane:

print "103\n";
