Steve Linton makes a lot of remarks with which I agree completely
on the state of GAP documentation and on the potential usefulness
of a workshop on GAP internals, then ends with

...
My provisional view (and I am quite happy to be persuaded otherwise) is that
the correct time for such a meeting is probably quite close to the release of
GAP 4.1, so that the instructional side of the workshop would have something
solid to work with.
...

It seems to me that the intended public would have a thorough
knowledge of the GAP language and would not need too much
'hands-on' experience, so maybe as soon as the 4.xx kernel is stable
might be the right time (i.e. maybe we should not need to wait until
the GAP 3.xx libraries have been completely rewritten...)
