Unable to infer array size if I don't repeat it twice

[dusky herald]

fails: foos: [_]?Foo = .{ null } ** ELEM_COUNT,
works: foos: [ELEM_COUNT]?Foo = .{ null } ** ELEM_COUNT,
How can I do this without repeating ELEM_COUNT twice?

foos: [ELEM_COUNT]?Foo = @splat(null),

Thanks!

Actually another related question; this is an element of another struct Bar:

const Bar = struct {
  foos: [ELEM_COUNT]?Foo = @splat(null),
};

how can I initialize a Bar with only one Foo without using ELEM_COUNT?

const bar = Bar{
  foos[0] ??? = .{...},
}

[hidden grove]

const bar = blk: {
    var bar: Bar = .{ .foos = @splat(null) };
    bar.foos[0] = something_else;
    break :blk bar;
};

So it's impossible in an initializer?

[hidden grove]

yep

but labelled blocks are great :)

[dusky herald]

Yeah, very flexible

[hidden grove]

you can do all sorts of complex initialization in them, without losing constness

and you can do it at comptime too if you want
