[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 bug47;

bool func(bool a, bool b)
{
    if (a) b = false;
    return b;
}

void main()
{
    assert(func(0,0) == 0);
    assert(func(0,1) == 1);
    assert(func(1,0) == 0);
    assert(func(1,1) == 0);
}
