No need for two statements there:
my @tmp_list = split(...);

Perl keeps a reference count of variables and since a reference to @tmp_list
is still in existence after the block ends the memory occupied by that
variable will still exist.
You have a bigger problem with the statement:
@full_list = (@full_list, [EMAIL PROTECTED]);
because you have two copies of @full_list in memory. You should use push()
for that:
push @full_list, [EMAIL PROTECTED];
