+
+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;
+
+yields

+ 4
