Since I spent most of my energy writing it, I’ll just link it: Reddit::Client Official Documentation.
I use it for all of my Reddit related scripts, so developing it isn’t just an intellectual exercise. All of the new functionality and fixes arose out of necessity. In fact, if any functionality is still lacking (and there are a few things), it’s probably because I haven’t had a need for it yet.
Feedback or questions can be sent to me at my email below or on Reddit to /u/earth-tone.
