Case of Pascal is better (2 keywords where "of" isn't that useful, begin-end are optional if you want more than one instruction, Pascal isn't case-sensitive):

Case X of
  1: Begin
        ...
      End;
  2 .. 10: Begin
        ...
      End;
  ...
  Else Begin
         ...
       End;
End; {CASE}

But D is backward compatible with C (unlike languages like Scala, that eventually D will need to take a look at), so this is an academic topic.
