    // perspective.   One crappy outcome of this design is it requires Dynamic and Static
    // scopes to be mutable for this one case.

    // Note: In Ruby 1.9 all of this logic can go away since they will require explicit
    // bindings for evals.

    // We only define one special dynamic scope per 'logical' binding.  So all bindings for
    // the same scope should share the same dynamic scope.  This allows multiple evals with
    // different different bindings in the same scope to see the same stuff.
