I thought the comparison was between embedding a Scheme or implementing your own sexp parser from scratch. Of course embedding a good sexp parser is also a valid option to consider, I'm not that dense. Granted that in this particular case the point seems to have been the exercise of implementing the parser itself so embedding a dependency wasn't a valid approach to begin with.
