Is there a more compact way to describe the opCmp function in the

Hm... what about:
return count < rhs.count ? -1 : count > rhs.count ? 1 : rank < rhs.rank
? -1 : rank > rhs.rank;
by reusing something like
auto opCmp(const Hit rhs) const
{
if (this.count < rhs.count)
{
return -1;
}
else if (this.count > rhs.count)
{
return +1;
}
else
{
return this.rank.standardOpCmp(rhs.rank)
}
}
A standard opCmp would be nice. Why wouldn't you use it for count as well?
