[fpc-pascal] Constants in generics

[Alexander Shishkin]

Thanks, now I`ve lost is a discussion again. What is the decision about 
syntax? Is "const" prefix and/or ": type" suffix required?


generic TList1<T, U> = class
   var data: array[0..U] of T; end;

generic TList2<T; U: Integer> = class
   var data: array[0..U] of T; end;

generic TLis3<T; const U> = class
   var data: array[0..U] of T; end;

generic TList4<T; const U: integer> = class
   var data: array[0..U] of T; end;
