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)

You are not required to understand it. Another monk pointed out how it can be implemented without any changes to the Perl6 core. I can do it as a module. (Which is all I was wanting in the first place.)

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?

A buffer, of course. Each buffer would be an instance of the buffer class from the module I want to create. I thought I was entirely clear from the outset that my primary intention was to implement buffers (as a module). buffer-local scoping is just one part of that.

My original message said:

So I was thinking, hey, with this nice flexible object model, could we implement buffers in Perl6 as a module and throw it on CPAN? So I started thinking about how that would work... A buffer, obviously, would be an object...

How is that not clear?

(I probably won't call the class "buffer", though, as that might lead to confusion. "textbuffer" perhaps, or "hunkoftext", or something. I don't need to decide the name right now.)
