Sargon,
One thing to keep in mind is that template instantiations are decided at compile
time. So you can't do anything like
void f(Color c)
{
uint64_t bb = AttackTable::ColorTraits<c>::pawnAT[42];
}
However, I think that this was clear to you. Other than that, I can't see from
the code you posted what went wrong. Could you post or send the code you tried
to compile?
Sven.
