I don't understand "you have no idea about arbitrary object." Obviously you would get a type of object based on the header in question. > Anyway, lets move forward.

This reads like, "Look, just use the API that you don't like because I already wrote some code." That's not going to sway me. What happens when someone wants a Date object for the Date header? Do we add header_date? Then header_rcvd for Received headers, and so on? This interface leads to either a proliferation of these things or to some line where we say, "well *these* headers are important enough and *these* are not." On the other hand, a generic mechanism is generic. You can always publish your work as a subclass, if you think it that popular acclaim will convince me I'm wrong. -- rjbs
