+ * ext/ext.c: Object#to_eet: Don't put the final chunk in a stream
+ again, it's not needed
+ * ext/ext.c, test/test_stream.rb: If Stream#serialize is called on
+ a stream that includes non-Chunk elements, BadElementError is
+ raised
+ * ext/ext.c: Tweaked for_each_prop; use rb_ary_push() to add
+ chunks to the stream instead of calling Stream#push
