Dustmited case code:

void main()
{
    int[] a = [3];
    int value = abs(a[0]);
    assert(a[0] == 3);
    writeln(value, " ", a);
}

Num abs(Num)(Num x)
{
    return x >= 0 ? x : -x;
}

struct File
{
    struct LockingTextWriter
    {
        this(File) {}

        ~this() @trusted {}
    }

    auto lockingTextWriter()
    {
        return LockingTextWriter();
    }
}

File stdout;

void writeln(T...)(T args)
{
    stdout.lockingTextWriter;
}
