I followed Elan's suggestion to try out list! series. Here is what I
did:
>> list: make list! [1 2 3 4]
== make list! [1 2 3 4]
>> first list
== 1
>> remove list
== make list! [2 3 4]
>> first list
** Script Error: Out of range or past end.
** Where: first list
What!!!
>> list
== make list! []
Oh, the series is completely empty!
Can anybody explain why remove all elements in the list instead of just
the first element? Remove block! series just one element at the head.
Why different?
