Does DMD currently do any analysis of references to a symbol in

so, be stored?

I'm guessing

    Scope::insert(Dsymbol*s)
    {
        if (VarDeclaration *vd = s->isVarDeclaration())
        {
            // ..


is of interest. Is there another member function called everytime 
a Dsymbol is referenced?

I'm guessing MODFlags plays a role here aswell.
