Thank you for your careful answer. As I understand, in order to compensate the 
std::hash simplicity you do additional hashing (bit mixing or modulus) in the 
container. May I ask, have you considered the other approach - to make the 
container simpler but add bit mixing to std::hash? Why you chose not to follow 
this path?
