ahh - Ok

std::pair<VariableData*, void*> m_x
...
ar << m_x

of course won't work- my mistake - since there is no way
to determine what the true type is.

So how about one of the following?

struct extradata {
...
};

std::pair<VariableData, extradata> m_x
std::pair<VariableData &, extradata&> m_x
std::pair<VariableData *, extradata*> m_x
std::pair<VariableData*, extradata  &> m_x
...
ar << m_x;
