-While complex arguments can be fed to most modules in Ansible, they should only be used where needed.  Note
-that variable interpolation works exactly as you would suspect, so you can use "${foo}" and so on in values
-inside of the dictionary you pass to "args".
+You can of course use variables inside these, as noted above.
 
-If both key=value arguments are given along with 'args', the key=value arguments take priority.  This technically
