We have almost all of readtable currently. We are missing the case
'slot'.

This is coming from the ansi docs shipped with gcl. Unfortunately not
yet completely implemented.

The standard dispatch-macro-character functions work, as does
copy-readtable, etc. What outside of readtable-case do you want to
do? My understanding is that everything should work but the case.

It should not take long to implement readtable-case. I'll try to find
time for it soon. It came up in the ansi-test suite recently too.
