In a language like Perl, it can be pretty hard to determine when a
variable is last referenced. Here's a simple example. When is $h last
referenced?
perl -le 'my $h = 17; print $h; my $i = chr <>; eval "print \$$i"'
Do you have your answer?
Now run it and type in 103. Then run it again and type in 104.
Were you right?
