Too complicated, I think. The solution is to "use" both packages,
the compiler must then detect ambiguities:
with Text_IO; use Text_IO;
with Dual_IO; use Dual_IO;
procedure Test_Use is
begin
New_Line;
end Test_Use;
* ObjectAda:
test_use.adb: Error: line 6 col 3 LRM:8.6(31), Ambiguous call,
possible definitions of New_Line appear at line 92 of file
ada.text_io.spc, line 58 of file dual_io.ads.
* GNAT:
test_use.adb:6:03: ambiguous expression (cannot resolve "New_Line")
test_use.adb:6:03: possible interpretation at dual_io.ads:58
test_use.adb:6:03: possible interpretation at a-textio.ads:169
