Any example anywhere of V3?

I've spent hours reviewing the API "docs". Ultimately, to repeat the plea I've read over and over again on this board:

I would simply love to see a WORKING example (IN ANY language) of how a website can add an email address to a given Constant Contact mailing list. It would go a long way to see one program that from start to finish authentic with Constant Contact via API V3, adds an email address to a list, drops the authentication token correctly.
