Yes this is what I'm targeting, a as direct translation as
possible.

You are being really helpful <3. You mentioned topics and ideas
that I forgot about. I forgot about Lucia Cojocarus talk, and
I have now added that to the proposal.

Thanks :)

I can not promise anything as I don't know what my future holds,
but currently I could see myself continuing this work after GSoC.

Sounds good, with all the comments from you and Kayomn I realized
that I had to improve most of the text, and refocus a few parts.
So the text is kind of messy right now.

We've finished the implementation of `_d_arraycast` as a template.  I followed essentially the same procedure in your propose.

1) https://github.com/dlang/druntime/pull/2264 - Add new template to druntime with unittests verifying the implementation

2) https://github.com/dlang/dmd/pull/9516 - Update DMD to call the template and remove calls to the previous runtime hook

3) https://github.com/dlang/druntime/pull/2535#event-2241980654 - Remove the no-longer-used, old runtime hook from druntime

I made the mistake of planning for betterC in (1).  It made things a little too complicated which delayed the implementation and required me to have to do a little back-and-forth with Walter on how to not rock the boat too much.  You've already stated you're going with a direct translation.  That's good.  This at least shows some of the changes that may be required to get a feature working in betterC in a followup PR.  It also shows how complicated things can get when considering betterC.  I still have to add DMD PR to verify the betterC implementation, but I'm a little on the fence about it.

Anyway, in addition to Lucia's PRs...

... it serves as a good case study.

Thanks again for all the help and the links :)

I'm happy with the proposal now, it took a bit longer than expected
but it is much better than the old one. I only have some small
nitpicks go though and fix. I will try to submit the proposal
tomorrow.

Feel free to look at it again if you want.
