Hi Paulo,

I would agree. I'm going to change both the List::Remove() and
Hash::Remove() *functions* to throw an error if the list/hash is
empty. The List and Hash::Remove *procedures* will just quietly return
(no need to throw an error), unless you actually specify an index (or
key) in which case it will throw an error.

I'll also try to add an IsEmpty() method for IDL 8.1.

Cheers,
