I think you should be wary of returning a simple scalar only when there is just a single item in the list. You will end up having to check to see if the return value is a reference before you know how to handle it.
I didn't design the calling interface to CGI::header() and CGI::redirect(), I'm just trying to encapsulate it.
Also, think about what the return should be if the list is empty?
For my anticipated uses with CGI.pm, the lists should not be empty: 1. CGI::header() -type argument defaults to "text/html". 2. CGI::redirect() -uri argument defaults to "http://localhost";. My constructors and set() methods can enforce such.
Why are you insisting on an existing class, especially if you are intending to extend it?
