Using a simple Bond<T> to propagate side effects

[JustinTulloss]

I'm having some trouble figuring out how to use a bond for things that are not necessarily value transforms.

For instance, if I want to change the height of my label based on the updated text, I thought I could do something like this:

textLabel.dynText ->> Bond<String>() { _ in
    textLabel.sizeToFit()
}

However, that seems to only fire once. Changing the textLabel (even via another bond) does not cause the function to fire again.

Am I missing something?

you need to retain the bond

Ok. Seems like I probably should have thought of that, but it wasn't obvious to me from the docs.

Thanks!

(And I see that it's explicitly stated in the docs now, it's just not actually spelled out in the examples)
