Hi jan
- having a class Selector that get evaluated into a symbol. You can then achieved selector namespaces, which does not incur a cost at execution.
Indeed we should just agree that this is the semantics we want for class extensions for example :)
Viewed this way, indeed :-)
Jan did you have a look at http://timelessrepo.com/refinements-in-ruby Because I would like to know if there are more selector or classbox oriented or something else?
Briefly. That post is more a "wow-that's-cool" sort of post rather than in-depth technical report. Looks like classboxes without local rebinding - that's what they say, after all.
Stef .
I do not understand the idea. Could you give an example?
Cheers, Jan
Cheers, Alexandre

I mused with a colleague about how I'd like to see "lexically scoped monkey patching", and he pointed me to some guys that want to add that to Ruby (http://timelessrepo.com/refinements-in-ruby). Note the inspiration for their work: ClassBoxes! (http://scg.unibe.ch/research/classboxes)
I remember reading the paper years ago, and started working through it again now. Something that's not clear to me is this: does ClassBoxes require VM-side changes? (Because it changes the method lookup, after all, searching packages for methods before working up the inheritance tree.) If so, how invasive are they? If not, do we have a ball-park estimate of how much work it would be to update ClassBoxes to a more recent Squeak/Pharo?
I'm more than happy to do the dogwork. I'd just like to know whether I'm signing up for months of work or not.
Thanks!
