This would need us to handle Array_Constructor (from fparser), and turn it into a literal (or literal subclass, maybe ArrayLiteral). Unless we have a use-case where we need to analyse these structures (e.g. during declarations for declaration ordering is a possibility) then I think there's no rush.
