The list at<br>
<a href="https://github.com/ghc-proposals/ghc-proposals/pulls?page=2&q=is%3Apr+label%3A%22Accepted%22+-label%3A%22Implemented%22" rel="noreferrer" target="_blank">https://github.com/ghc-proposals/ghc-proposals/pulls?page=2&q=is%3Apr+label%3A%22Accepted%22+-label%3A%22Implemented%22</a><br>
lists PRs marked as accepted but not implemented. It is an<br>
overapproximation, because we only add the implemented label if someone<br>
tells us to. So it is hard to tell, but looking at the list (especially<br>
the second page with the older proposals), for a few of them I can’t<br>
remember seeing a MR on GHC. But of course that’s just an impression.<br>
<br>
Do you see value in deliberating over proposals without an indication<br>
that someone actually plans to try to implement them?<br>
<br>
Cheers,<br>
