Heh?  "Sugar" doesn't mean "infrequently used".

Yes, it's true that Ada 95 was criticized in that way.
However, I think such criticism was complete nonsense.
Whatever "object oriented" means, surely it doesn't have
anything to do with notation.

It's fine to use the prefix notation if you think it's more readable,
but you shouldn't attach any semantic significance to it -- it really is
just syntactic sugar.

You can't use an operation of an object to create that same object,
because it doesn't exist yet.
