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 <.
