I'm not wedded to the :: digraph, I prefer the concept.  :: was nice
because it re-used a similar concept from C++.  No other digraph jumps
out at me.  Some other possibilities (I don't care for any of these):

        Global          Nested
        ------          ------
        :>variable      scope:>variable
        *>variable      scope*>variable
        ->variable      scope->variable
        ?>variable      scope?>variable
        &>variable      scope&>variable

Or perhaps variations using <.
