+    A slightly special case exists for importing sub-modules.  The
+    statement
+
+        import os.path    
+
+    stores the module `os' locally as `os', so that the imported
+    submodule `path' is accessible as `os.path'.  As a result,
     
-    To avoid confusion, importing a submodule `as' another module is
-    not allowed. When importing a submodule in the normal way,
-    
-        import os.path
-        
-    The actual name stored locally is `os', not `path', and the newly
-    imported module can be referenced as `os.path'.  When introducing
-    the `as' keyword, it is unclear whether the `os' module or the
-    `path' sub-module should be stored `as' the requested local name.
+        import os.path as p
+
+    should store `os.path', not `os', in `p'.  The current
+    implementation does not yet support this.
