IndexedType has a operator bool() const and bool is comparable with operator<:

#include <stdio.h>
class Foo {
public:
    operator int() { return -1; }
    operator int() const { return -1; }
};

int main()
{

    Foo f1,f2;

    if( f1 < f2 ) {
        fprintf(stderr, "smaller\n");
    } else {
        fprintf(stderr, "bigger\n");
    }
}
