NDC Does C++ Countdown!

It was my pleasure to run a small workshop style session at the excellent NDC-London conference. I ran a fun C++ game which parodies the popular UK TV gameshow Countdown.
  • In the TV version contestants take turns picking 9 random vowels/consonants and finding the longest word in 30 seconds.
  • In my version contestants take turns picking 7 random tokens from 5 categories: (keywords, identifiers, operators, punctuators, literals) and writing the shortest C++ program using all 7 tokens in 8 minutes.
Contestants write their code in customized cyber-dojo sessions which automatically:
  • checks which tokens have been used
  • tells you the size of the program
  • allows everyone to see all the submissions in the review
The rules:
  • tokens must be the correct type; eg you cannot write "." or ... for a dot operator
  • whitespace does not count towards the program's size
  • additional tokens are allowed
  • the program must compile
  • the program is not executed
  • warnings are allowed
In one round Phil Nash selected these 7 tokens:
const vector tokens =
{
    ".",                  // operator
    "switch",             // keyword
    "snafu",              // identifier
    ",",                  // punctuator
    "\"salmo\"",          // literal
    "goto",               // keyword
    "!",                  // operator
};
and the winning solution (54 characters long) was:
union X { X* x; };
X snafu() {
  l: switch (X().x,!"salmo"); goto l;
}
In another round Hulgar Frydrych selected these 7 tokens:
const vector tokens =
{
    "catch",              // keyword
    "->",                 // operator
    "[",                  // punctuator
    ";",                  // punctuator
    "--",                 // operator
    "foobar",             // identifier
    "operator",           // keyword
};
and the winning solution (53 characters long) was:
class c {
  c operator->(){ 
    foobar:
    try{
    }
    catch(c x[]){
        x--;
    }
  }
};
Can you create shorter versions?
