Well, this function is about `yield`'s taking * multiple values. Consider following user-defined class: * * ```ruby * class Foo * include Enumerable * * def each * yield :q, :w, :e, :r * end * end * * Foo.new.each_with_object([]) do |i, j| * j << i # ^^^ <- What to expect for `i`? * end * ``` * * Here, `Foo#each_with_object` is in fact `Enumerable#each_with_object`, which * doesn't know what would be yielded. Yet, it has to take a block of arity 2. * This function is used here, to "pack" arbitrary number of yielded objects * into one. * * If people want to implement their own `Enumerable#each_with_object` this API * can be handy. Though @shyouhei suspects it is relatively rare for 3rd party * extension libraries to have such things. Also `Enumerable#each_entry` is * basically this function exposed as a Ruby method. */ VALUE rb_enum_values_pack(int argc, const VALUE *argv); RBIMPL_SYMBOL_EXPORT_END() #endif /* RBIMPL_INTERN_ENUM_H */
