My apologies. Interval *is* an indexable class (though it should always 
have 0 indexed instance variable). For me, #basicNew: does create a new 
instance. What error do you get when creating one that way?

Also, are you sure you want is #isVariable and not #isIndexable? 
#isVariable will also get you the NSCs. I think you'll have trouble with 
NSCs using #_basicAt: and #basicAt:put:, you probably need to use #do: 
and #add: to enumerate and build these.
