How about creating a context object or struct, with a single property to which 
you assign a copy of the array (or, alternatively, a computed property that 
dynamically returns the contents of the array)? Then you’re not making an 
UnsafePointer of the array itself, and it probably shouldn’t get unnecessarily 
assigned to.
