Indeed. What I was thinking would actually need generic functions,
bounded generics and generics with type-erasure ;-)
So you'd write, say:
>>>>
type generic TAlias1<T: TObject> = class(TObject)
function Alias1: T;
end;
function<T: TObject> Alias1(Source: T): TAlias1<T>;
<<<<
And yet you wouldn't be able to name the alias...

PS. I can't believe Embarcadero went for ":" instead of "=" for
declaring bounded/restricted generics :-/
