Using SystemVerilog foreach with multi dimensional arrays

[subbdue]

Iterating over multi-dimensional static and dynamic arrays in SystemVerilog is easy

logic [7:0] arr[][][];

arr = new[10];
foreach (arr[i]) arr[i] = new[20];
foreach (arr[i,j]) arr[i][j] = new[30];

foreach(arr[i,j,k]) arr[i][j][k] = $urandom_range('h10, 'hff);
