• Remove the type parameters from JSRef.

• Turn declarations like this:

  type Foo = JSRef Foo_
  data Foo_

  into

  newtype Foo = Foo JSRef

• ToJSString / FromJSString were removed. ghcjs-dom has some similar utilities, but a different API. Seems like a good idea to keep them around. See ghcjs/ghcjs-base#30

• GHCJS.Foreign.newObj became JavaScript.Object.create (and getProp, setProp, etc got moved there too).

• release became releaseCallback

• Callback stuff dropped the retention parameter, and changed the Bool to OnBlocked. True becomes ContinueAsync, and False becomes ThrowWouldBlock

• You should just use Data.Coerce.coerce instead of castRef

Thank you! This is quite helpful. What about arrays?
