Sounds good. Do you opt for creating a second open list?

I don't know, but it was there.

I have naver used it, and I can't see why you would. But it seems that 
someone wants to.

I was wondering about this. It seems that it is implementation defined or 
undefined, since inheritence and even non-trivial constructors precent a 
struct from being POD. So you can't cast a pointer to the class to a 
pointer to the first member.


struct a{ float d[4]};
struct b{ float d[4]};

I think in the above case you can cast a pointer to an "a" to a pointer to 
a "b".

However, TooN makes use of reinterpret_cast a lot everywhere, so I don't 
think it matters having it there.

Well, Ville Kyrki became a known user by complaining...
