Trying to manipulate 'typeof' return strings, preferably at compile-time.

e.g. to produce struct B below (intended to have an A sub-struct), from A_Ptr alone.

struct A {
   int AFld1;
}
A* A_Ptr;

struct B {
   int BFld2;
   typeof(A_Ptr)[0..($-1)] ASUB; // Idea is ASUB of type A, from A_Ptr of type A*.
}

But this fails with 'can only slice tuple types...'.

Suggestions?

I think what you really want is

typeof(*A_Ptr) ASUB;

the typeof thing returns the type you'd get from the code inside
