Hi Felix
This is one of the standard REBOL gotchas. The assignment list: [] creates
a literal block and all subsequent references are to the same block. That
is why it just gets longer and longer. To do what you want use
list: copy []
which will create a new empty block each time it executes.

Hi!
I have the following code:
num: 30
to: load %file
until [
list: []
print length? list
loop num [
elem: first to
if elem [ append list elem ]
to: next to
]
print length? list
print "---"
tail? to
]
It gives
0
30
---
30
60
---
60
90
---
90
120
---
120
150
Shouldn't list length be set to zero by
list: []
???

Of course I'm crazy, but that doesn't mean I'm wrong.
