After a few hours trying to figure out why the compiler didn't catch this, I finally figured it out. You have to add `@safe`.

import std.stdio;

int[] x;

void func(scope int[] a) @safe
{
    x = a;
}

void main() @safe {
    func([0,1,2]);
    writeln(x);
}

This is one of the things really ticks me off about D; it has all the wrong defaults.

At a minimum, the documentation needs clarification. I encourage you to file a bug report against the documentation at http://issues.dlang.org/

Oh! Surely adding @safe makes the expected behavior.

According to your advice, I try to post a bug report.

Thanks!
