No, because then it fails for ulong.
It's those bloody C implicit conversions.
hmm... works for me:
---
struct A
{
bool opEquals(ref const A y) const
{
return false;
}
bool opEquals(long y) const
{
return true;
}
}
int main()
{
A a;
ulong b=42;
assert(a==b);
return 0;
}

Yes, but the code is incorrect if b is larger than long.max.
The problem is that values in the range long.max+1..ulong.max
get turned into values in the range -1 .. -long.max-1
How can you distinguish them?
