[svn r213] Fixed: foreach on an object seems to have been broken, the issue was that DMD generates an implicit delegate with conflicting types for 'this'. Fixed: string switch runtime support had wrong param types. Fixed: string switch on a temporary slice was broken.

module bug23;
void main()
{
    int i;
    delegate {
        i++;
        delegate {
            i++;
        }();
    }();
    printf("%d\n", i);
    assert(i == 2);
}
