Can functions only return 1 value?
I'd like to return 3.
Do I just have to wait until arrays?

Yes, functions can only return 1 value.

There won't be an easy way to return 3 values until arays are implemented.

There are some harder ways to fake it.

One is to use global variables for the other two return values.

Another is to return an NPC reference or a Slice handle, with the return values packed in the "extra" data.

Neither of those is particularly easy to use, but they might be good enough for now?

I'm wondering whether we should support unpacking multiple return values. The new language features on that page are only suggestions, and for the most part have not been discussed. Some of them are probably too radical.

I've used arguments as an improvised way to gain more values out of a script before.
