[ExM Users] 2D arrays

[Tim Armstrong]

Yes 2D arrays are supported with the same declaration syntax as Swift/K.
You're trying to declare a 2D array with key types i and j in each loop
iteration.  The compiler is correctly pointing out that i isn't a type.
You need to declare it outside of the loops then assign it inside the loops.
