Joel,
I followed your suggestion and pushed as considering that the rest was ok.
Hope this is fine.
Joel and Eli,
Thanks a lot for your review and valuable feedback!
Best regards,
-Fred

I don't think we've been using the [] syntax for parameters, but I don't see a problem with that per se.
What I'm wondering, however, is the size of the array. In particular, you'll need, at least, to update the documentation. But if the size is actually statically known (which it seems is at most 4 elements), then perhaps it might be worth just saying it in the parameter type declaration...
Other than that, the patch looks good to me.
