I don't understand how you expect it to work, and it's still not clear
it would be terribly useful.

Well, that's what the language files do.  In general, you need the CCL
to be loaded when the coding system definition is loaded, if only
because it will be necessary to fill the safe-chars property if it
builds a table.

[chinese.el?]  Regardless of orthogonality, the coding system either
has to be defined in a preloaded file or autoloaded.

 WL> Why not?  

The requirements from the language list are processed by an explicit
call to `set-language-environment'.  Also, the CCL engine can't use
anything from the Lisp engine that could trigger GC (like `load'), and
CCL can refer to programs via properties of symbols, not just from
`setup_coding_system' (or whatever it is).

 WL> I think this won't work.  

It works fine for its intended application.  It was just an example of
something you can do to extend coding conversion.
