Hello, see this test program:
procedure Test_Ambig is
type X is (Data, Meta);
procedure Foo (Data : in Natural) is
Z : constant X := Meta;
begin
case Z is
-- when Data => null;
-- when X'(Data) => null;
-- when X.Data => null;
-- when X (Data) => null;
when Meta => null;
end case;
end Foo;
begin
null;
end Test_Ambig;

I've tried the four commented lines (though I'm pretty sure three of
them don't make sense) to get this to compile with Gnat for linux (3.4.2
and all GAP releases). I think this is one of these cases where the
answer is obvious but you need the eyes of other person. Is there some
way to qualify "Data" as the enumeration type instead of the procedure
parameter? Or is this simply a no-no caused by hiding? Thanks!

These are Standard.Test_Ambig.X, Standard.Test_Ambig.Data, &
Standard.Test_Ambig.Meta.

These are Standard.Test_Ambig.Foo and Standard.Test_Ambig.Foo.Data.

This is Standard.Test_Ambig.Foo.Z.
Generally, you can leave off the "Standard." :)
