}
void mrb_example_gem_init(mrb_state* mrb){
  struct RClass *foo;
  foo = mrb_define_class(mrb, "Foo", mrb->object_class);
  mrb_define_class_method(mrb, foo, "bar", bar_method, MRB_ARGS_NONE());
}

@param mrb The MRuby state reference. @param cla The class where the class method will be defined. @param name The name of the class method being defined. @param fun The function pointer to the class method definition. @param aspec The method parameters declaration.
