+func ToChan[T any](ctx context.Context, iter *Iter[T], errptr *error) <-chan T
+    ToChan copies the members of an input iterator to a new Go channel. If

+    writing to the channel is placed there and can be read after the end of the

 func ToMap[K comparable, V any](ctx context.Context, inp *Iter[Pair[K, V]]) (map[K]V, error)
     ToMap consumes all the elements of an iterator over key-value pairs and
     returns them as a map. All but the last of any pairs with duplicate keys are
