>From that post:

> The solution is to add some symbol that explicitly marks the array as not
> complete, so both the compiler and > the person that later reads the code
> knows some items are missing.
> 
> If no item is missing the compiler probably has to generate an error again:
> 
> int[2] arr = [1, 2, ...]; // compile-time error
> 
> I think that syntax is explicit and readable enough. A problem with this idea is
> this syntax is probably not > used often. On the other hand leaving that trap in
> the D language is not good at all.
> 
> The idea of the dollar symbol can't be used with the ellipsis symbol:
> 
> int[$] arr = [1, 2, ...]; // compile-time error again
> 
> Note: for me this syntax with $ is more commonly useful compared to the "..." syntax.
