Comment:

 The fact that imported globals are widely used in Wordpress doesn't
 mitigate the inherent drawbacks of the overuse of globals and the global
 singleton pattern in development. We need to be able to scope variables to
 templates for the same reason we need to scope variables anywhere, because
 the global scope makes knowledge of the state of a variable difficult, and
 reduces the modularity of code. At this point, getting variables into
 template parts seems to involve building a maze of functionality around
 managing imported globals, just to duplicate the functionality of local
 scope.

 I'm currently working on multiple projects that require building frontend
 implementations of complex data structures, many of which contain repeated
 nested elements. I end up wrestling with a choice of either building
 enormously complex templates to handle the data object, or breaking the
 elements into smaller templates and relying on imported globals in some
 fashion. I've run into a number of situations where tracking the state of
 multiple globals made testing and debugging much more difficult than they
 needed to be. While I'm able to solve these problems, the solutions are
 often byzantine, which is frustrating given that scoping is a solved
 problem that helps code conform to the principles of OO design.
