What's the advantage of using a hash with keys being the line numbers over using an array? 
@array = <FILE>;   # reads each line of FILE into an $array[$element]

print "Line 10 of FILE: $array[9]\n";

Each line is individually addressable as-is. Hashes don't buy us any efficiency (in fact, it's quite a bit less efficient).
