in reply to basic question:how to print a reversed array from STDIN

The reason why is what ikegami said. So try this: 
@getnew=reverse(map { chomp; $_} <STDIN>);

or 
chomp(@temp=<STDIN>);
@getnew=reverse(@temp);

Whatever you like best. I prefer the first version.

    I think this is neater: 
    chomp(@getnew = reverse <STDIN>);

    I cringe when I see map or grep modify $_.

      I agree with you in regards to grep, but map? It's sole purpose is the modification of $_.

        No - map returns a new list, so changing $_ makes little sense. Either use a foreach if you want to do an inplace modification of a list or return a fresh list and try to keep away from changing the list alias :)
