`orelse` in tuple does not compile

[giann]

const std = @import("std");

test "orelse in tuple" {
    var opt: ?u32 = 1;
    std.debug.warn("A tuple: ({}, {}, {})\n", .{ 1, 2, opt orelse 3 });
}

λ zig test tuples.zig

/Users/giann/tmp-code/tuples.zig:5:67: error: duplicate struct field: '2'
    std.debug.warn("A tuple: ({}, {}, {})\n", .{ 1, 2, opt orelse 3 });
                                                                  ^
/Users/giann/tmp-code/tuples.zig:5:67: note: other field here
    std.debug.warn("A tuple: ({}, {}, {})\n", .{ 1, 2, opt orelse 3 });

Looks like the same thing as #3882
