Test code:
----
struct S
{
    this(A)(auto ref A a){}     // line 3
}
void main()
{
    S s = S(10);
}
----
Line 3 causes error 'Error: auto can only be used for template function
parameters'.

Workaround is follows:
----
struct S
{
    template __ctor(A){         // workaround
        ref typeof(this) __ctor(auto ref A a){ ...; return this; }
    }
}
