Oh look, a tuple-exp implictly converted using structural typing methods. D does not parse the comma-exp anymore.

Hey, cool idea. We’re need to have tuples first, though.

So how does this print 3?

import std.stdio;

void main(){
  int n;
  n++, n++, n++;
  writeln(n);
}

my bad, I thought it was at least deprecated ;)

I remember now that what is deprecated is to use the result of the comma-exp. I just wanna say, off-topic, that if D wants tuples, it would be time to fully deprecate the exp, depending on if you want tuples in 3 (deprecate now) or 6 years (do nothing for now).

I expect tuple to come before that

It is sad to see D being stuck like that

Yes.

A tuple expression would probably require brackets:

A comma expression result can't be used. I think it can only be used as an expression statement, or in the for Increment clause. Are there any cases where it could conflict with bracketed tuples? dmd accepts a comma expression with parentheses, but that would presumably be a 'has no effect' error if it was parsed as a tuple.

No, I cant see one either. Looks like the comma-exp is actually not the blocker ;)

Well this was a clumsy way to say "sorry I was wrong". However I'm pretty confident about the fact that tuples in D will take age to be accepted and implemented. I challenge you to post me an email notification when the following will work with an official D release:

static assert((0,1,2)[1] + 2 == 3);

You can find my email by scrutinizing the messages of the main commiter of https://gitlab.com/styx-lang/styx.

Sorry for the supplemental provocation but let's go: I'll try to keep the address alive for at least 5 years.

Hope to get a message soon 🤠
