Arrays (technically, slices) in D are essentially this struct:

struct Array(T) {
    T* ptr;
    size_t length;
    // operator overloads
}

So when you have int[][], each element of the outer array is 
an Array!int. These, as simple structs, are copied about, so 
that changing one does not change another.

Thank you for the reply, I think this explanation should be 
added to the top of https://dlang.org/spec/arrays.html

Then people (esp with C/C++ background) can easily understand 
D's array behavior.

A good explanation of D's arrays (which should really be called 
"slices") is available in the "Articles" section of dlang.org:
