Sounds like a bug. First, there's an incompatibility between AA value type and the type being assigned: the value type of `lookup` is a static array, whereas a slice is a dynamic array. But since the compiler allows this assignment, it should work. I suspect there's a frontend bug somewhere in how assignments of slices to static arrays are implemented. T -- MAS = Mana Ada Sistem?
