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.
