Right, it does not make sense for REPL, SLDB or inspector. But as you can see from the example above: It makes a lot of sense for .lisp files, and I use it every day.
I didn't understand your example. Perhaps you're looking for an extra command to make the current connection buffer-local in a buffer.
Ok, say stop where you fall off. --- Example --- I have two different lisp images running in one emacs. One business-logic-image, and one web-server-image There is one source file for image the business-logic-image (lets call it the business-logic-file), and a different file for the web-server-image (lets call it the web-server-file) When I press C-x C-e in the business-logic-file, I want the lisp-form to be evaluated in the business-logic-file When I press C-x C-e in the web-server-file, I want the lisp-form to be evaluated in the web-server-file Then if I shall do a change in my system that requires changes in both web-server and business-logic, then I have to change default connection, at least once. If the development-cycle requires several iterations. Either because I want to improve the code, add features, or debug. I would have to change default connection back and fourth several times. Then it would be better to have the connection buffer-local, so I would not have to change it in every development cycle. ------
And I don't want to make the current default-connection buffer-local. In my experience, this would require many more steps of interacting with Emacs to get the desired result. (step 1: selcect a different default-connection. Step 2: make it buffer-local. Step 3: go to a different-buffer, that does not have a buffer-local default-connection. Step 4: select the original default-connection, to restore desired behaviour. So that we don't forget this later. Step 5: jump back to the special customized buffer, to complete your work)
I want a different connection from the current default-connection to be the buffer-local default-connection. The reason that I don't what the current default-connection to be buffer-local, should be obvious. If I wanted to use the default-connection, then I would not have to make it buffer-local.
Slime-cycle-connections making the new connection buffer-local means for example that making another connection the default connection via slime-list-connections will lead to surprises.
There will be no surprises. You will anyway need to keep track of your connection. You can do that by looking at the connection-name in the mode-line. You will also have to have to know what kind of source-code you are evaluating, then you would know which lisp-image it should be evaluated in.
Additionally, buffer-local connections can become stale, rendering the .lisp buffer useless.
If the buffer-local connection become sale, you will avoid running lisp-commands in another random default connection. You would then have to restart your lisp-image, or connect again. Then select the connection as buffer-local for that buffer. Anyway this is not an hindrance, to implement this functionality. It's merely an interesting beginners hacking assignment, to pop up buffer with the connection-list if the connection is broken.
