Ts-toolbelt: O.Writable doesn't work well with generics after update to 3.8.4

[xaviergonz]

Since 3.8.4 this got broken, it used to work in 3.8.3

    class Foo {
      readonly s: string = "hi"
    }

    function someFn<F extends Foo>(foo2: F) {
      const wfoo = foo2 as O.Writable<F> // here it complains this is invalid
      wfoo.s = "ho" // here it complains s is not there
    }
