Decl striving mightily to hit CPAN

Turns out the Decl namespace was reserved by mistake, sort of namespace shrapnel from a project a couple of years ago. They're working on resolving it.

I'm looking at a "walk" tag/action that would justify (in my mind) adding another version number for the next upload. I might finish it up tomorrow; it's essentially just a built-in that permits easy traversal of directories or other directory-like hierarchical data.
