reduced:

---
struct StoreAny {
    ubyte[16] store;
    this(T)(T value) {
        *(cast(T*) store) = value;
    }
}

struct SomeStruct {}
enum StoreAny someEnum = StoreAny(SomeStruct());

void main() {
} 
---

but code is invalid anyway. I suspect that the intention was more

  *(cast(T*) &store) = value;

which CTFE cant do anyway.
