Wright's posting here a few days ago of the : sequence of instantiations needed to obtain a simple structure with the : Booch components clearly indicates that they fail this requirement. I can't see why in _Ada_ this is a problem. You have to laboriously write things up in all sorts of unexpected places, unexpected to the newcommers at least. Like certain arrays in a record: you need to declare a type first. That is, multilevel instantiation, considered an _implementation detail_, is quite in the Ada spirit from that point of view. At least to me. (If I wanted nice data structures almost for free, I might as well chose a language that has them :-) Georg
