-    Note that the lazy loaded module location is a _string_, not a _type_. 
-
-    To reference the _type_ we'd have to use a JavaScript import statement to get the module symbol, 
-    which loads the module immediately, defeating our intent to load the module later.
-
-    A string, on the other hand, is just a string. It has no side-effects.

-  The module location strings in this app identify module _files_, not module _classes_.
-  That works because each module class is marked as the default export in its file.

-    _Remember to use_ `export default`_ for the lazy loaded module class.
-    Continue to use `export` for all other classes.
+    A lazy loaded module location is a _string_, not a _type_. 
+    In this app, the string identifies both the module _file_ and the module _class_,
+    the latter separated from the former by a `#`.
