You'd check the function's safety when reading the file, of course, as
it is done currently for the `printer' arg of ses-cell.

Exactly: it allows denial-of-service kinds of attacks, but you can
probably already get similar problems some other way (e.g. provide
a `printer' argument that's a circular structure, so that the safety
checking doesn't terminate).
