Hi,

I uploaded a new version of the Kernel package (Kernel-ul.403) to the 
Inbox. It adds the #cull: protocol to BlockClosure. #cull: is pretty much 
like #value:, but can be send to blocks without arguments. The 
implementation contains #cull:, #cull:cull:, #cull:cull:cull: and 
#cull:cull:cull:cull:. There's also a new version of KernelTests 
(KernelTests-ul.140) which implements tests for these methods.
The pros and cons of these methods can be found here: 
http://lists.gforge.inria.fr/pipermail/pharo-project/2010-February/022151.html
(though I think portability will be an advantage soon).
If nobody disagrees I'll add these to the Trunk in a few days.


Cheers,
Levente
