here you have a hash ref named $hashRef

here you are trying to access the 'list' slot of a hash named $hashref which
on course is different than $hashRef you declared above. not to mention
that you are not treating $hashref as hash reference, you are using it as a
hash. which one is it? is $hashref really a hash reference or just a hash?
is $hashRef the same as $hashref?
if $hashref is the same as $hashRef and it's really a hash reference, try:
for(@{$hashRef->{list}}){
print "$_\n";
}
if $hashref is NOT the same as $hashRef and it's really just a hash, you
have the right syntax:
for(@{$hashref{list}}){
print "$_\n";
}
