Fix SPARK!

There is no usable languages without overloading. Since you mentioned ()
[meaning aggregates], think about them used for ordering:

   (x)

returns what? For each type and subtype of x there is some "()". They all
are overloaded. Do you wish to annotate each of them?

   I := Integer'(1 + 2) * 4 ?

But what about +,-,*,/?

Since the dictionary of any language is far less than the number of
entities an average program in that language describes, you simply cannot
avoid some kinds overloading.
