There's `staticArray` to solve this issue [1].
[1] https://dlang.org/phobos/std_array.html#.staticArray
It works only for the `int` type and above (and other types as structs).
example with short:
---
extern(C) void main()
{
import std.array;
auto a = [0, 1].staticArray!short; // error
}
---
To fix that, I need to cast every element:
---
extern(C) void main()
{
import std.array;
auto a = [cast(short) 1, cast(short) 2].staticArray!short; // ok
}
---
With a tweak, it's possible:
T[n] staticArray(T, size_t n)(T[n] val...) { return val; }
auto arr = staticArray!short(1, 2);
Though the syntax isn't as nice...
