It's a special case of something that's unmentioned: creating temporary values in aggregates.

That's a great point. If you missed it, consider this:

my $item = 'wibble'; my @things = qw /foo bar baz/; local $things[1] = 'qux'; # Legal local $item = 'wobble'; # Dies with 'Can't localize lexical variable + $item'

-xdg
