+Another idea for relative numbers could be to have a coord object with

+__newindex could catch a table being assigned - test.foo = {widget = '...', acl='...'}

+    the table itself is passed to __call as the first argument, the rest of the arguments follow.

+      foo has to be a table value though, with a metatable
+      and the rest of skang is treating test.foo as a nil value so that __index and __newindex work.  B-(
+    test itself is a table, so all is not lost -
+      test{'foo', widget='...', acl='..'}  ->  __call(test, {'foo', ...})
