 In F# we can do
 {{{
 #!div style="font-size: 120%"
   {{{#!haskell
   match x with
       | 1 | 2 | 3 -> "123"
       | 4 | 5 | 6 -> "456"
   }}}
 }}}

 It will be nice if we have an extension which allows us to do
 {{{
 #!div style="font-size: 120%"
   {{{#!haskell
   case x of
        1 | 2 | 3 -> "123"
        4 | 5 | 6 -> "456"
   }}}
 }}}
