Mutually recursion version.

struct A
{
    static B b;
    alias b this;
}

struct B
{
    static A a;
    alias a this;
}

struct C
{
    int opSlice(size_t, size_t){ return 0; }
    int opSlice(size_t, A){ return 0; }
}

void main()
{
    C c;
    c[0..A];
}

This has nothing to do with method overloading.
It's a stack overflow caused by aliasthisConvTo.
