I'm slowly adding R6RS functionality to Kawa. It may be a bit
early, but it would be useful to have some idea of R6RS
functionality that is most likely to be removed, deprecated,
or substantially changed.  Or conversely: What R6RS functionality
is relatively settled and uncontroversial?  That would help
implementers in terms of what R6RS functionality is relatively
safe to implement vs what to defer.

Obviously:
* Object/record system.
* Eval/phasing functionality.

What else?
* Exceptions/conditions?
* Bytevectors?
* I/O?

I'm assuming that SRFI-99 is a statement from at least Clinger
as to what R7RS records should look like, which suggests at
least the R6RS procedural layer is mostly safe ...
