If all goes well, readtable-case will suddenly become our number one
priority. There is some readtable mechanism available in GCL already,
isn't there?

For the life of me, I can't figure out how to modify a readtable with
the functions that exist in GCL.

If we have to use some non-ANSI, GCL-specific readtable commands for the
time being, that's no big deal. If we have to wait a little while to get
a GCL with a readtable-case, we can live with that, too. If, however,
there is no way to work around readtable-case in GCL and you think it
would take six months to get a working implementation, now would be the
time to find out.
