// A namespace-scope declaration or definintion of a non-line function
// template, a non-inline member function template, a non-inline
// member function of a class template or a static data member of a
// class template may be preceeded by the export keyword. If such a
// template is defined in the same translation unit in which it is
// declared as exported, the definition is considered to be
// exported. The first declaration of the template containing the
// export keyword must not follow the definition. (meaning that export
// can't beredeclared as non-export??)
