mrjt, yes, I do have very close situation.

UPD: Finally U++ forced me to switch back to VectorMap. It seems like Index is not designed for such cases (but these cases happen very often IMO). Two big drawbacks:
1) Unable to find element by hash
2) Unable to change element, due to I have only (const T &) in return. But this seems too strict. Changing the object doesn`t necessary change it`s hash value. This approach forces one to declare all members as mutable.
