Here are a few ideas for future Sage projects in error-correcting codes.

Needed in Sage is

- a rewrite in Cython, for speed,
- special decoding algorithms, also in Cython,
- for special decoders, it seems to me that one either needs

- more classes (eg, a CyclicCodes class), each of which will have a decode method, or
- another attribute, such as a name (string) which can be used to determine which decoder method to use.

- codes over Rings (Cesar Agustin Garcia Vazquez is working on this)
- codes defined from finite groups fings – for example split group codes,
- a fast minimum distance function (followed by a fast weight distribution function), valid for all characteristics.

It seems more “Pythonic” to add more classes for decoders, but I am not sure.
