I.e. the behaviour of X declared of being TType depends on where it is
declared. That's great. Let us consider this:
function Func return TType is
function Func_Func return TType is
begin
return X : TType;
end Func_Func;
Y : TType := Func_Func;
begin
return Z : TType := Func_Func do
Y.E1; -- This is not like X?
Z.E1; -- An this?
end return;
end Func;
--
