Maybe you got this this from Zaxo's answer, in which case, this will be a redundant post, but I think Zaxo was a little gentle in his statement.

If your going to use Tie::File, don't open and <read> it yourself as well.

Imagine how confused your dog will get if you start barking at the postman yourself:)

Either tie the file to an the array, and use the array

Or

open the file and <read> it.

but don't do both.
