IIFE conversion?

[CrazyPython]

let name = () => {
    declarations;
    return rvalue;
}()

to

type name;
{
    declarations;
    name = rvalue;
}

Thanks for the idea!

One thing though: if there are multiple returns inside IIFE, that makes things a bit ugly, because we would have to break from the block using goto in that case.

In overall, I think the idea is sound, but I would propose to only optimize simple IIFEs with that approach - ones that don't return values and don't have any return statements inside.
