Just tested, using the same code I used earlier, substituting in each new eval block one at a time without using exit(), i.e.: 

#!/usr/bin/perl

use warnings;
use warnings::unused;
use strict;

my $foo = 42;
my $bar = 43;
eval '$'.'foo++';

Result for eval '$'.'foo++': 

Unused variable my $bar at ./warntest.pl line 8.

[download]

Result for eval 'print q{$foo++}': 

Unused variable my $foo at ./warntest.pl line 7.
Unused variable my $bar at ./warntest.pl line 8.
$foo++%

[download]

(the % is inverted on my terminal, and is a lack-of-newline marker)

Result for eval '$cond ? $foo : $bar': (blank).

Double-checking that my original example didn't cause a funny result because I wrapped it in exit, I checked eval q[$foo++]; 

Unused variable my $bar at ./warntest.pl line 8.

So it looks like it does what you'd expect, other than the first example, and more or less exactly what I want.
