tl;dr: the currently proposed syntax options are:

struct S

int a = 2, b = 4, c = 6;

void foo()

bar(S(c: 10)); // Option 2

So the struct-initialization DIP has been stalled for too long and I
think it's time we finally get this story done.
I personally prefer option 2, but this might be in conflict to named
arguments which we hopefully see in the near future too. Hence, I'm
leaning forward to proposing Option 1 as the recommended Option for the
DIP (that's also what the PoC DMD PR implements). What's your take on this?

Talking about future potential features, Option 1 could be in conflict
with a tuple with named elements. Option 2 could be in conflict with
named parameters, true, but named parameters could also have a different
syntax, i.e. foo(a = 3, b = 4), this is what Scala is using.
