digitalmars.D.learn - how to initialize an array of struct

My code is as following:

struct Point {
        float x, y, z ;
};

int main ()
{
        Point[3] pts = [
                {1.0, 0.0, 0.0} ,
                {0.0, 1.0, 0.0} ,
                {0.0, 0.0, 1.0}
        ];

        return 0 ;
}

But, the compiler report "Error: array initializers as expressions are not
allowed".

Then, how do I initialize an array of struct ?

That message's pretty messed up: array initializers look like [1.0, 0.0, 0.0] in D.

Replacing the middle lines with these works: Point(1.0, 0.0, 0.0) , Point(0.0, 1.0, 0.0) , Point(0.0, 0.0, 1.0)

Move the definition out of main (note that ; after the struct isn't required): struct Point { float x, y, z; } Point[3] pts = [{1.0, 0.0, 0.0}, {0.0, 1.0, 0.0}, {0.0, 0.0, 1.0}]; void main () {} Bye, bearophile

The fact that *does* compile just makes the error message all the more crazy...

It should compile inside of main if declared static. It's just the error message that's a bit off.

It is perfect, thanks.
