It is unclear what you would want 'static static' to do in more complex cases. For
example, should 'static static' within a member function template of a class
template mean that the variable is shared across all combinations of instantiations
of the class template and of the function template, or merely that it is shared
across instantiations of the function template within each given instantiation of the
enclosing class template ?
It seems to me more sensible to place the static variable explicitly in the scope
you want it (such as in a namespace or as a static member of a class or class
template). That way you have full clarity. If you need to control the sequencing of
its initialization, use the Meyers singleton idiom.
