If, as you suggest below, there was a static/shared option, I'd think the warning would be printed if you copy/paste an [array define] *without* said option set. Asking for a shared object would make it explicit the "multiply defined" aspect is required.

Yeah, that's basically what I was thinking, but also for regular arrays as well.

In that case, I'd say it's a "lazy load" singleton situation where the first shared instance of that name is loaded and subsequent instances are pointers back to the shared instance until they are all deleted, then we start over. I guess it would be like reference counting.

Yeah, I was thinking something similar: a mechanism for sharing the underlying data behind the instances when needed as an option without disturbing current behavior. It not an aspect that's needed much for regular patches, but I've already run into a few abstractions that would benefit from sharing this kind of data, ie. static lookup tables, etc.
