Really?

Actually, this is a problem in TooN. Vector<Dynamic> and Vector<Resizable> 
are copy constructible, but operator= will only work if the vectors are 
already the same size. Vector<Dyanmic> is not default constructible, but 
Vector<Resizable> is.

I don't know what the precise requirements of the STL are. I think making 
Vector<Resizable> resize automatically on a call to operator= will make it 
completely safe to store in all STL containers.

Thoughts, anyone?
