Right, I've cooked a little script to interpret .js files directly.

I ran the sputniktests[1] from google using the attached guile-es-parse
script, which only tests the parser.

  python tools/sputnik.py --full-summary --command ./guile-es-parse|tee log

The result is impressive (full log attached):

  === Summary ===
   - Ran 5246 tests
   - Passed 4410 tests (84.1%)
   - Failed 836 tests (15.9%)

Where the failed tests have

   - 245 unicode errors (unicode literal is not supported)
   - 393 rbrace errors  (see below)
   - 39 Math.LN2 errors (see below)
   - 159 remain to sort out

The rbrace errors are from

   function test() {}
   // Syntax error: unexpected token :  in form rbrace

   function foo() { this.bar = function() { return 0; } };
   // Syntax error: unexpected token :  in form rbrace

I also tried to compile the parsed tests, but halted because too many
errors like

   Object.prototype.toString = function () {return "something";};
   // No applicable method for #<<generic> pput (6)> in call (pput
   // #<unbound> toString #<procedure 1e1c438 ()>)

I thought the tests won't run correctly without this.
