This can't be right, can it?
type
TBird = class
procedure Fly;
end;
TEagle = TBird; // alias
procedure TEagle.Fly;
begin
end;
It does depend on what you expect an Type-Alias to be.
If you expect the compiler to generate an compatible class then your
example must not be compilable.
If you expect an alias die make the Typenames "TEagle" and "TBird"
equivalent it is no problem for the compiler which name you use at what
place.
In any case I would judge such code as "bad style" - programmers should
avoid doing so.
