Having not heard a user request for global variables, I'm a little fuzzy on the use case. However, if I understand correctly what is suggested is a combination of:
1. a new built in type with two features. 2. a slight variation on the set index, where instead of silently ignoring a "duplicate" FS being added to the index, an exception is thrown. 3. custom APIs for working with the features of this type. Is this right? Eddie
