thanks!

To my knowledge, no such operator exists. Sorry.
You can dereference a single reference to an array. But you can't
dereference a list of references to scalars.
Best you could do would probably be s

It sounds to me like you're looking for the exact opposite of the \
( ... ) behavior.
My friend is trying to do this:
#!/bin/perl
$a = 1;
$b = 2;
$c = 3;
@l = ( \$a, \$b, \$c );
# This is the line we need help with
# Is there a way to tell Perl that @l[0] is a reference
# and we want to assign what it refers to the number 4.
# i.e. ${$l[0]} = 4;
# but for the whole list in @l
