Nesting multiple writable types is still not supported. |

I guess there's still one problem: the setter on the wrapper type accepts the inner type, that is, CC: @YaLTeR |

Yeah, it would be good if the generated public-facing methods had newtype in their signatures. |

Would this also already handle a Mutex<Option<ThreadGuard<Paintable>>>? Asking for the Option there. It's a write-only property so I think that potentially works because there's From<T> for Option<T> but I think it doesn't work in practice because you'd need to call from() twice?

Adding a discussion item for this somewhere so we don't forget
I guess there's still one problem: the setter on the wrapper type accepts the inner type, that is, i32, not MyInt(i32).

Would you mind rebasing this one? |

I can rebase, but I don't think this is ready to be merged. There are still some unresolved things, as pointed out by the unresolved comments |

fixes #983
enables support for a correct handling of
ThreadGuard, therefore supersedes #968.In general, this kinda enables two-level nesting: this makes supporting newtypes trivial (conceptually, they are a nested type).
The change is backwards compatible
