Sorry for the noob questions, but

import std.stdio;

struct Foo {
int x;

void main() {
auto array = new Foo[10];
auto i = array.length;
foreach(Foo f; array) { f.x = --i; write(f.x);}
writeln();
foreach(Foo f; array) { write(f.x);}

Here: Foo f is not a reference but a copy of each array element. Use
foreach( ref f; array)

}

gives me:

PS E:\DigitalMars\dmd2\samples> rdmd bug.d

0000000000

Also,

void main() {
auto array = new Foo[10];
--> for(int i = array.length; i > 1; i--) { array[i].x = i; }

Arrays indices are 0 based, thus last index is array.length-1.

writeln();
foreach(Foo f; array) { write(f.x);}
}

throws core.exception.RangeError@bug(8): Range violation on the line
with the arrow.

What am I doing wrong ?
