Re: RFC: modules for generic unordered sets and mappings

       gl_set_search               O(n)     O(1)

       Here the search method returns a void *, with value (void*)-1
       denoting "not found". Hmm, or should the search method better
       take a 'bool *' argument???

If 'gl_set_search' is merely testing the membership of an element in a
set, would not suffice to make it to return a boolean value, like in:

 bool gl_set_search (void *key);
