Speaking of this, I was just recently thinking that the possibility to
mess up your file while exporting is quite dangerous especially as the
user may not expect this to happen. It happened to me several times
while developing some, admittedly buggy, exporting scripts of mine,
often because of wrapped data being manipulated in some contrived way.

Now, wouldn't it be interesting to have a "safe mode" that would grant
read-only access to data structures, when set? Sure, most exporters
have to generate temporary data , so they actually *need* write
access. Still, I feel that something could be done in this respect.
Any comments on this?
