If documentation will guarantee NRVO is applied in simple cases (i.e. no copy
construction occurs) structs with disabled default construction will be able to
be returned from functions (currently it is not guaranteed to compile):
---
struct S
{  disable this(this); }

S makeS()
{
    S s = S();
    return s;
}

void main()
{
    S s = makeS();
}

Also Issue 10371 have to be fixed first.
