+Data writer
+===========
+
+Data writer enables serialization of data as string characters written
+to output stream. Same encoding rules that apply to data reader also apply to
+data writer.
+
+Additionally, data writer will provide informative representation of data
+types which can not be parsed by data reader (`builtin function`,
+`builtin syntax`, `function` and `syntax`).
