Hi All,

I am new to Squeak, and haven't done anything with it yet but I have been
reading the news group to catch up on what is going on with Squeak.

In VAST (IBM's VisualAge for Smalltalk) a LookupTable can not have a nil
key but a Dictionary can.  Dictionaries contain Associations and they have
no problem with a nil key so I guess Dictionaries don't have a problem
either.  In past versions of VAST (before 5.5.2) LookupTables could have a
nil key but that changed.
