 Priority:  major                    |             Milestone:  someday

 Keywords:  spock, unreachable code  |  Estimated difficulty:
-------------------------------------+--------------------------------
 The spock runtime (both spock-runtime.js and spock-runtime-debug.js)
 contains unreachable code.  Example:

 {{{
  ____25call_2dwith_2dsaved_2dvalues = t1355;    // set! %call-with-saved-
 values
 ...
     var t6 = t1358;
     var t1360;
     if(t6 !== false) {
      return k1100(t6);
      t1360 = undefined;
     }
 ...
 }}}

 The assignment {{{t1360 = undefined;}}} is never reached, as there is a
 return statement immediately before.

 Tip to find such cases: search for {{{" = undefined"}}} in spock-
 runtime.js or spock-runtime-debug.js.

 I don't know exactly how this affects code, but the firebug console prints
 thousands of warnings because of this.
