Function that can return a value

This would be extreamly usefull, especially for people who don't wan't to exit the Scratch Project making UI.

An example:

First, declare the funccion:

Then calling it:

This already exists:

In that case…duplicate.

No, what I refer to is first defining a funccion like so:

and then calling it like so:

There are work arounds, but they are messy.
One is to create a variable, set it is the funccion and read it from the out side:

You do this and then call the funccion from the code.

I think that this would remove all that mess of creating variables for returning.

It looks like you already made a topic about that here.

Yes, it is a duplicate of #1.
Also, there is a chance of it being in scratch 3.

A solution that comes to my mind would be the following:

We create a special variable named RETURN (for example) and then in every function we want to return a value we instead save that value into that variable

And when we call the function to use the return value we make use of the RETURN variable.

I haven't explore this solution a lot so I don't know if it is prone to error, but even though I wanted to share it and I hope it is useful for someone.
