Documentation must guarantee no copy construction occurs on struct
initialization and `init` assignment or usage of any struct with disabled
default construction is not guaranteed to compile:
---
struct S
{ @disable this(this); }

void main()
{
    // Copy constructed from temporary?
    S s = S();

    // Copy constructed from `S.init`?
    S s2 = S.init;

    // Assigned from `S.init`?
    s2 = S.init;
}
---

E.g. in C++ one can use `S s(...)` syntax for this purpose.
