I did some digging in the conference, but failed to come up with the relevant thread. IIRC the main disadvantages were that they were inefficent to implement, and were bad for code readability. I say "they", becase just overloading assignment is not enough, you need an operator to overload read accesses too.

I don't remember a discussion that came to that conclusion. Got a pointer to it, or can you reiterate the disadvantages that were discussed then?
