Pascal (Delphi-style pascal) has a generic solution for this. It's 
called an "array of const". You use it like this:

***
procedure p(args: array of const);
var
   i: longint;
begin
   for i := low(args) to high(args) do
     case args[i].vtype of
       vtInteger:
         writeln(args[i].vInteger);
       ...
     end;
end;

begin
   p(["string",'c',1354]);
end.
***

I suppose this is all explained in the reference manual, though I'm not 
sure.
