+Ansible has pretty basic precedence rules for variable overriding. We already have
+some tests above about group order.  Here are a few more.
+
+   * -e variables always win
+   * then comes "most everything else"
+   * then comes variables defined in inventory
+   * then "role defaults", which are the most "defaulty" and lose in priority to everything.
+
+Given the above rules, here's a test that a -e variable overrides inventory, 
+and also defaults, and role vars.
+
+etest = from -e
+
+Now a test to make sure role variables can override inventory variables.
+
+role_var_beats_inventory = chevron 5 encoded
+
+Role variables should also beat defaults.
+
+role_var_beats_default = chevron 6 encoded
+
+But defaults are lower priority than inventory, so inventory should win.
+
+inventory_beats_default = narf
+
+That's the end of the precedence tests for now, but more are welcome.
