<<package Commands is
procedure Execute is abstract;
end Commands;
This compiles with Gnat 3.10, but what does it mean? Could it
be overridden, and how would you override it?
>>
It does not mean much, but it does not mean nothing. For example, it
means that a child of Commands will not be able to have use visibility
on a parameterless procedure Execute from a with'ed package.
But why should it mean antying? There are lots of ways to write
meaning;less nonsense in any language.
type x is range 1 .. 0;
for x'Size use 0;
does not seem very meaningful, but is certainly legal!
