What is that doing being the scenes? If it’s creating a whole new array and appending it then it’s probably pretty inefficient and hopefully can be optimized away.

Since dynamic array helpers work could you expose a function that adds an element to the array (an grows it if needed) so we could make helpers for it? Pushing a value to an array is perhaps the most common function used for lists so it makes sense to get that right imo.
