Actually, I have made it explicitly non-copyable via private
copy-constructor, and uses of the internal ifstream are by reference only.
Also, the iostreams are already non-copyable due to some base-class having
private copy-ctors, but this makes error messages a little more readable.
Thanks for the warning though.
