The user-visible functions are OP_function_first through
OP_function_last (see operations.h, also a generated file).

Perhaps a function-based external interface to the list then?
e.g.:

    size_t 
    expr_get_function_cnt (void) 
    { 
      return OP_function_cnt; 
    }

    const char *
    expr_get_function_name (size_t idx)
    {
      assert (idx < OP_function_cnt);
      return operations[idx + OP_function_first].name;
    }

    const char *
    expr_get_function_prototype (size_t idx)
    {
      assert (idx < OP_function_cnt);
      return operations[idx + OP_function_first].prototype;
    }

(There will be some duplicates for function names, but prototypes
should be unique.)
