I am making a state management container for my max apps. I'd like to make it follow the generic applicable syntax so that one can call it as if it's a hashtable, allowing code using this to be unaware of implementation. So I want to implement a setter and getter for my function to be able to do:<div><br></div><div>;; call my setter </div><div>(set! (my-state-thing :foobar) 99) </div><div><br></div><div>;; call my setter</div><div>(my-state-thing :foobar) </div><div><br></div><div>I apologize if this is just basic scheme ignorance!</div><div>thanks</div><div>iain<br><br><div><br></div></div></div>
