[REBOL] Re: Limiting Serie sizes (native!)

Hello Maxim,
Yes im using something like that right now, but My idea behind was more like:
* Protecting runaway code
- Wrong functions can fillup block cq. memory in milliseconds
* Limiting the code in the begining in the header ie. REBOL [ blocks/limit 65535 ]
* Controlling static ends, that saves extra functions for controlling serie lengths.
* Perhpas dynamicly extending/descreasing the limit during serie use?
But on the other hand I can emagine the structure of rebol
to suffer under this enhancement too, its not dynamic anymore, BUT
if you could control memory size by limiting serie sizes??
I think the idea above could be a contradiction on the idea Carl has about the
dynamic behaviour of rebol ;-)
(R)egards,

-> > list: [1 2 3 4 5 6 7 8 9 0]
-> > head clear at list 4
-> == [1 2 3]

-> maybe this function helps in what you want to acheive?
->
-> clipped-append: function [series data maxlen][][
-> return all [((length? series) < maxlen ) (append series data)] ; or call
-> throw if you want an error
