Ok, makes sense.

Well, I have not looked into the coding guidelines, yet. I'll look into
that. Re-Using existing libraries, where it makes sense, however is
always the way to go (for that reason I'm already using Dpkg::Version ;)

Hmm. I'm not really sure, if ::Status would be the right name, but
on the OTOH you, as a dpkg maintainer, know better.
Besides that: The idea in general is good. I guess I'll rewrite DPKG::Log as
Dpkg::Log to be a common class, implementing the common interface for
dpkg logfiles and Dpkg::Log::Status extending that.
