[svn r123] Fixed some typeinfo module name mismatches. Fixed D-style varargs returning through pointer. Fixed converting nested function to delegate. Added std.string and std.format to Phobos.

module aa2;

void main()
{
    long[float] aa;
    long* p = 2.0f in aa;
    assert(!p);
    aa[4f] = 23;
    p = 4f in aa;
    assert(p);
    assert(*p == 23);
}
