Now, You are a very nasty person :-)
Nope, at least by my knowledge that's not possible, but advocating to
find the balance between readability and shortness you're left with
a. accessing
$item->[0], $item->[1]
for very short loops without repetitive use if $item->[nn]
b. using what you already do
my ($item1, $item2) = @$item
but - ignoring the fact that you probably just normalized your
problem - you should use more specific names like
my ($name, $id) = @user_info;
for longer functions
Since you're thinking about that way of shortening your code, I guess
you're a more or less experienced programmer that is used to - and not
afraid of - using the language's idioms. So consider above reply as a
guide for the *real* beginners and not necessary for you. :-)
