This doesn't seem to follow the proposed design discussed in #47
I think time is just one case with private fields.
It would great if we could extend this to handle more cases with the design discussed in #47

I agree. I just quickly added it for myself, and thought why not open PR. Is anyone actively working on generic solution?

Currently no one is working on the generic solution, so you are free to go for it, if you would like.

Also if you would like to propose a different solution, we can also discuss in it #47
But, my main concerns with this solution is adding more and more special cases over time, which I would prefer not to support. I hope that makes sense.

It makes sense. But even with generic solution available, I think it's worth having support for stdlib types like time.Time out of box

Good point, how many stdlib types are there with private fields? I am sure time.Time is the most popular, but I wonder how many special cases we would have to handle to provide this smooth experience for users.
