No, for good or bad, but ":=" is not a procedure in Ada.
One point, the formal generic parameter T_Item is declared as "private".
This means that its actual counterpart must have assignment. So you can
write:
generic
type T_Item is private;
package Toto is
...
end Toto;
and use assignment within the body of Toto:
package body Toto is
...
X, Y : T_Item;
begin
...
X := Y;
...
end Toto;
