293 | Note that, in both the above, $_ is in scope within the code block, as well as |
294 | being passed as $_[0]. As per CORE::map and CORE::grep, $_ is an alias to |
295 | the list value, so can be used to to modify the list, viz: |
296 | |
297 | use Moose::Autobox; |
298 | |
299 | my $foo = [1, 2, 3]; |
