Array attributes unsupported

Example of this at the bottom. I'm not sure why attributes on arrays are not supported and whether this is a deliberate choice. I can't promise anything soon, but if you're happy to accept a pull request for this I can have a go at implementing it sometime.

By the way, impressive work with this project!
