+
+Note that, in both the above, $_ is in scope within the code block, as well as 
+being passed as $_[0]. As per CORE::map and CORE::grep, $_ is an alias to 
+the list value, so can be used to to modify the list, viz:
+
+    use Moose::Autobox;
+
+    my $foo = [1, 2, 3]; 
+    $foo->map( sub {$_++} ); 
+    print $foo->dump;
