-- what is the difference between int[] x; and int[int] x; ????
int[] x; is like
struct _Int_Array
{
size_t len;
int* ptr;
}
_Int_Array y;
int i = 5;
x[i] = i; // this and the line below crash or assert, due to a
null pointer
*(y.ptr +i) = 5;
are both the same;
int[int] is a completely different beast. is it a hashtable that
maps ints to int.
its a lot closer to int[string] than it is to int[]
