As for the crash Thorsten got, that's now fixed in CVS and
snapshots: attempting to use "append" within a function will
provoke an error (as does "open", which has always generated an
error -- but when we banned "open" originally we overlooked the
need to ban "append").
Nostra culpa -- or "our bad", if you prefer. I had a feeling there
might be an example in the Gretl User's Guide where "append" is used
inside a function and now I've found it, in the "Gretl and R"
section under "Technical details".
In that case we just got lucky and there was no crash. I need to
think a bit more about whether there's a way to support "append" in
functions without breaking the "encapsulation" we require of
functions (basically meaning, no unintended side-effects).
