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

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];
}
