Function debug_xd

This function allows you to attach extra data to any object for temporary debugging purposes. It essentially allows you to carry some data around that is tied to / associated with an object. It is especially useful for objects that make it difficult to hackishly modify custom properties in moments of debugging.

Example

const john = create_person();
debug_xd(john).name = "john";

const jane = create_person();
debug_xd(jane).name = "jane";

// later on, we detect an error originating in some person object and we'd like to log its name
const person = get_arbitrary_person();

try {
  person.do_something();
} catch(e) {
  console.log(debug_xd(person).name, "caused the error");
}}
