While experimenting with "undefine", I discovered, that
even quite important functions, like "write" or "display"
can be undefined. The problem is, that calling them
after they have been "undefined", leads to an
endless regression, displaying a Segmentation fault,
when finally interrupted.
If I "undefine" list:
(undefine list)
and call it afterwards:
(list 1 2 3 4)
I get the expected "ABORT: (unbound-variable)
I would be glad to help out, to fix this.
Be greeted,
Fabian Schütz

Can you explain why you need to undefine those functions?
Unless there's a compelling need, I'm afraid it's unlikely anyone will
work on this, because most developer focus is now on 1.9/2.0.
Thanks,
Neil

Indeed, `undefine' doesn't exist in 1.9/2.0.
If you still have questions, Fabian, let us know how we can help you do
what you need to do without using undefine.
