Re: The Trunk: Kernel-mt.1371.mcz

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

Re: The Trunk: Kernel-mt.1371.mcz

Really nice! I'd just add a return to behave like a normal #value in case the
non-local return doesn't happen:

^self value: [ :ret | ^ ret ]

Thanks,
