February 26, 2019 State of DIP 1000 | ||||
---|---|---|---|---|
| ||||
How is DIP 1000 doing? The document [1] says 'status: draft' and 'pending a rewrite', though there already is an implementation behind the -dip1000 flag and I've seen people using it. How much is implemented? Should I already compile with it and use scope? The last forum thread I found "On the future of DIP1000" [3] is from 2016. What's the current roadmap? Relatedly, can I already use 'in' for function parameters? "It is recommended to avoid using in until it is properly defined and implemented. Use scope const or const explicitly instead." [3] Is that up to date?

Unless something has changed recently, in doesn't mean scope at all at this point - even with -dip1000. It was decided to not make it mean scope with DIP 1000, because doing so would break a lot of existing code - though some folks were very vocal in complaining about that. So, maybe that will change (especially since DIP 1000 is already pretty disruptive as it is), but as I understand it, even if you use -dip1000, in will mean the same thing as const, and AFAIK, there are no plans to change that. But I haven't been paying close attention to dmd PRs, so it's possible that something has changed.

That's a pity, I was hoping to abbreviate 'const scope' with 'in' in my parameter lists. Was that discussion on this forum?

I'll add that to the DConf agenda.
