[docs] [issue23232] 'codecs' module functionality + its docs -- concerning custom codecs, especially non-string ones

[Walter Dörwald]

Walter Dörwald added the comment:

That analysis seems correct to me.

Stateless and stream codecs were the original implementation. 2006 I implemented incremental codecs: http://bugs.python.org/issue1436130

The intent was to have stateful codecs that can work with iterators and generators.

When Guido began reimplementing the io machinery for Python 3 he used incremental codecs as the basis.
