How would I disable the following?

Disable the struct's default constructor, which implicitly
disables struct literals for it [1].

struct A
{
int a;
string b;
@disable this(); // Disable the default constructor ->

// @disable default constructors with N(N>=1) arguments
Structs have only a single default constructors (with zero
arguments) - which you can disable (as shown above); you were
using struct literals [2].
I'd like to force the user to set fields explicitly, so as to
make it more safe to add / move fields
If I understand you correctly, that is what you get when you
@disable the default constructor (again, there is only the zero
arguments one).
You will have to initialize your structs, explicitly, then,
though, i.e. `A a = A.init`.
