 - Maybe utilize serde
 - Look at how clap handles states between macro calls
   - They operate on a singleton lol
-  - This would need to store All traits and their functions
+  	 - We should, too
+	 - Providing both a builder and derive interface makes sense
+	 - Needs a list of traits and one for functions
+	 - latter one should be created from the first with a macro
+	 - should provide a method to match a call to these functions
 	 - It should also own (locked) Stdin, Stdout and Stderr (or any one Read and two Write objects)
-  - This bad boi would also implement the main loop for the cli application.
