AA invalidating pointers and references..?

[simendsjo]

unittest
{
        auto a = [1:2];
        auto p = 1 in a;
        // can p be invalidated by rehashing?
	// That is pointing to a different item or a memory location used for 
other things?

        auto b = a.rehash;
        
	// The spec also says it orders in place, but returns the reorganized 
array...
        // Is the spec right? That it rehashes in place and returns a reference 
to
        // itself?
        assert(a is b);
}

unittest
{
        auto a = [1:2];
        auto p = 1 in a;
        a.remove(1);
        // the memory for p can be reassigned by the gc,
        // so this is undefined behavior.. right?
        assert(*p == 2);
