+        // in Mocha are done with `fn`s that take a `done` callback, and call it with either nothing (success) or an
+        // error (failure). We want to add another paradigm for async tests: `fn`s that take no arguments, but return a
+        // promise. Promise fulfillment corresponds to success, and rejection to failure.
+
+        // To do this, we translate promise-returning `fn`s into callback-calling ones. So Mocha never sees the promisey
+        // functions, but instead sees a wrapper around them that we provide. The only trick is, how and when to insert
+        // this wrapper into a Mocha `Runnable`?
+
+        // We accomplish this by intercepting all [[Put]]s to the `fn` property of *any* `Runnable`. That is, we define
+        // a setter for `fn` on `Runnable.prototype` (!). So when Mocha sets the `fn` property of a runnable inside the
+        // `Runnable` constructor (i.e. `this.fn = fn`), it is immediately translated into a wrapped version, which is
+        // then stored as a `_wrappedFn` instance property. Finally we define a getter for `fn` on `Runnable.prototype`
+        // as well, so that any retrievals of the `fn` property (e.g. in `Runnable.prototype.run`) return the wrapped
+        // version we've stored.
+
+        // We also need to override the `async` property, since the Mocha constructor sets it by looking at the `fn`
+        // passed in, and not at the `this.fn` property we have control over. We just give it a getter that performs the
+        // same logic as the Mocha constructor, and a no-op setter (so that it silently ignores Mocha's attempts to set
+        // it).
