Here's something else that I find confusing:
>> list: [ 1 2 3 4 ]
== [ 1 2 3 4 ]
>> list2: next list
== [ 2 3 4 ]
>> clear list
== []
>> list2:
== [ 2 3 4 ]
>> next list2:
** Script Error: Out of Range or Past End
About every other operation I try with list2 errors. Exceptions are that I can assign
it to another variable and print it.
The exceptions are what confuse me. After clearing list, why does list2 print anything
at all?
Is this part of the garbage collection bug people mention? (Is the infamous garbage
collection bug documented yet?)

Robert,
empty? is kind of confusing, since it's just a synonym for tail? and doesn't
really tell you if there are no elements in the block, as there might be some
before the index point:
>> test-block: tail [1 2 3 4 5]
== []
>> empty? test-block
== true
>> head test-block
== [1 2 3 4 5]
You can always use:
>> empty? head test-block
== false
to find out if test-block is really empty.
See you,
