SuggestionListEnumeration?  What exactly will that do?

I suggest you just copy what is done with String{List,Enumeration} But 
instead of returning a "const char *"  return a "const Suggestion *" 
object.  Suggestion should be a structure something like

  struct Suggestion {
    const char * word;
    size_t word_size;
    float score;
  };
