Cool, nice utility - even though it does not support good readability of your code for sure :-) I have always used "thisContext return" for a similar result. :-D


What about supporting a return argument here as well, like:

self value: [ :ret | ^ ret ]

?


This could increase the usefulness of #valueWithExit, but on the other hand, all clients would need to send #cull: or #value:. Any opinions? :-)


Best,

Christoph
