You are missing the whole point: It is just the problem that some 
("automated"?) data types are not fully documented! How do I know which 
type behaves how? Do I have to guess it (as I did now)? You are always 
saying that you cannot do this and that with these and other types but 
there is no clear documentation what exactly you can do and what you can 
*not* do and what the compiler does in the background.

If all this knowledge would be visible *before* trapping into the 
pitfalls (after painful debug sessions) then the power of these types 
could be very useful. But now it is blind flying.
