+// example, this:

+//  }
+//
+// should be replaced with:
+//
+//  var foo = {

+//  }
+//
+// to do this, it clones the parameter array and the body of the object generator
+// method into a new FunctionExpression.
+//
+// this method can be passed any Function AST node path, and it will return
+// either:
+//   a) the path that was passed in (iff the path did not need to be replaced) or
+//   b) the path of the new FunctionExpression that was created as a replacement
+//     (iff the path did need to be replaced)
+//
+// In either case, though, the caller can count on the fact that the return value
+// is a Function AST node path.

+// argument that isn't an AST node path), it will throw an error.
