I'm trying to use features in a Safe compartment but they're not being recognized. Here's an example using Perl 5.12.2. 
use feature qw[ say ];

use Safe;

# works here
say "Hello!";

my $cft = Safe->new;
# allow all opcodes
$cft->deny_only();

# doesn't work here (expected result)
$cft->reval( 'say "Hello Again!"' );

# explicit load of feature, but doesn't work (unexpected result)
$cft->reval( 'use feature qw[ say ]; say "Hello Again! 2"' );

And here's what it spits out: 
Hello!
String found where operator expected at (eval 5) line 1, near "say "He
+llo Again!""
    (Do you need to predeclare say?)
String found where operator expected at (eval 7) line 1, near "say "He
+llo Again! 2""
    (Do you need to predeclare say?)

Does anyone have any experience with this?

Thanks,
Diab

Update: I should be clearer about the question:

How does one enable features in a Safe compartment? My example code seems to indicate that a simple use feature doesn't do anything within the compartment. Am I mising something?
