void f() {
void[] arr;
size_t* _length = &arr.length; // Error: arr.length is not an lvalue
void** _ptr = &arr.ptr; // Error: cast(void*)arr is not an lvalue
}

What is the case not to behave like a struct of two elements?
Workaround:
---
size_t* arrayLengthRef(T)(ref T[] arr) {
return (cast(size_t*)&arr);
}
T** arrayPtrRef(T)(ref T[] arr) {
return (cast(T**)&arr) + 1;
}
