Unfortunately, that would mean producing a specialised template routine
for McSimulation::value() (and others) as we cannot instantiate both
result_type of Array and result_type of double using begin() and end()
arguments. That would take us back to the beginning of this email
chain...
I personally would go for a constructor of Array(const
std::vector<double>&) for simplicity. Would you agree?

Neither. You can use the existing
Array(ForwardIterator begin, ForwardIterator end);
and pass the begin() and end() of the vector.
