Looks like we could use shorter argument names fairly easily. Maybe that's a job
for the minifier though. I think it would be nice (but larger) if we emitted
some newlines in the generated constructors too. Something ala:

   {'': function StringBufferImpl(...) {
     this._buffer = _buffer;
     this._length = _length;  
    },
    ...
   }

There's really no reason not to.
