This is incorrect. Pointers *are* allowed in @safe code. 
Pointer *arithmetic* is not allowed.


--T

void main() @safe
{
        int a = 1;
        int *b = &a;
        *b = 2;
        assert(a == 2);
}

does not compile for me with Error: cannot take address of local 
`a` in `@safe` function `main`

so there must be more restrictions in @safe code
