Array of structs construction

[bearophile]

I'd like to write code like this (the constructors of the structs 
must take 1 argument):

// some imports here
void main() {
    BigInt[] data1 = [5, 6, 9];
    Ranged!(int,5,10)[] data2 = [5, 6, 9];
    Nibble[] data3 = [1, 2, 15]; // Nibble.sizeof == 1
    alias Typedef!int Mint;
    Mint[] data4 = [5, 6, 9];
}

Do you like this feature?


Scala accepts a similar syntax:

// Scala code
object Main extends App {
  val data : Array[BigInt] = Array(10, 20, 30)
}


Currently in D you write this, it's not handy if you have many 
items:

// some imports here
void main() {
    auto data1 = [BigInt(5), BigInt(6), BigInt(9)];
    alias Ranged!(int,5,10) R; // a short name
    auto data2 = [R(5), R(6), R(9)];
    auto data3 = [Nibble(1), Nibble(2), Nibble(15)];
    alias Typedef!int Mint;
    Mint[] data4 = [Mint(5), Mint(6), Mint(9)];
}


Or you duplicate the arrays to avoid the bit liberals:

import std.bigint;
void main() {
    auto aux = [5, 6, 9];
    auto data1 = new BigInt[aux.length];
    foreach (i, a; aux)
        data1[i] = BigInt(a);
    // ...
}

Bye,
