You can have expressions of types of any complexity returned from a functio= n, as parameters, as operator parameters etc. Catch up! > That in practice means that the language is garbage collected. That's only relevant for languages that do most of their memory management = through heap. Much garbage is randomly created and need to be collected in = an asynchronous way. Ada has more powerful ways to manage memory, and it's automatic as well. Mostly it's through stack; the eventual heap garbage is collected in a dete= rministic and recursive way, invisible to the programmer, through finalizat= ion. This avoids the memory leaks/jams you meet sometimes with all-heap-all= ocation-and-garbage-collection.
