digitalmars.D - State of DIP 1000

reply Dennis <dkorpel gmail.com> writes:
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.
