Yes, absolutely - although I've heard rumors that /someone/ just
discovered a bug that may cause a crash instead of a parse error if
arrays of arrays are used and mistakes are made ;)

Perfectly fine there.

As a side note, it might be worth mentioning that `Array1[2][3]` now
holds a /copy/ of `Array2`, not a reference.

I doubt that's what you're actually seeing, because that exact construct
works perfectly fine here.
