Since it is already decided that it would be <> I didn't mix into the 
discussion anymore. However, I'll make a comment on this.

Params are passed to a procedure define like

   procedure MyProc(param, param, ..)

Arrays are declared like

   A: array[0..9] of ...

And generics.... they are soly defined by the fact that a type has <> in it.

That is imo inconsequent.
