In that first example, the following
int[] slice = cast(int*)malloc(10 * int.sizeof)[0 .. 10];
doesn't actually compile.

You would compile it as
auto slice = cast(int*)malloc(10 * int.sizeof)[0 .. 10];

So actually
auto slice = cast(int*)malloc(10 * int.sizeof)[0 .. 10];
slice ~= 1;
generates an error because you can't append an int to an int*.
