Yes, this shows why the idea of a hidden parameter (the protected object =
self) is bad. The object should have been passed as a plain parameter to
all operations of its type.
protected type T is
procedure Foo; -- More operation of T than others...
end T;
procedure Bar (X : in out T);
It is annoying that Foo and Bar being both operations of the type T have
different status.
