There would be problems in implementation of generics with shared code if
equal were always compositional. Certainly a consideration (it would mean
that equality had to be passed in for all types, quite expensive).
Second: it IS possible to define equality on non-limited types in Ada 83
using the generic trick. This trick is well known, and widely used, so you
cannot ignore it in considering upwards compatibility.
