Re: Re: Implementing (elisp-like) buffers in Perl 6: how to do buffer-localisation of arbitrary package variables?

You're still not making enough sense to make this workable. (And, like it or not, I'm the person who has to understand it--if I don't, you don't get it)

Emacs has the concept of a buffer and everything centers around it. That's fine. What perl construct are you proposing take its place? A class? A closure? A method? A file? Should it be tied to data and happen when that data is manipulated? If so, then what do you do when two pieces of data both override the same stuff?

Perl is not a text editor, and text editor metaphors don't always translate over. This would be one of those cases.
