I'm roughly on the same place.  i find #t perfectly predictable: #t+1 is nil and #t is either occupied, or zero.  that's all.  all the talk about "you never know if a table is a valid sequence unless you generate it yourself!".... is just like dynamic types, you either write defensive code (check everything), or write pretty code and blame any error on the caller.
