does anybody know where function (global-environment environment) in get-setf-expansion for sicl-env is defined or comes form, maybe I am just tired but I cant find it

no-defun-allowed: I saw that you are giving a presentation for the online Lisp meeting. Congratulations!

I did not, I had said I would need to think about what to present and left it at that.

OK, I think SICL has a condition system. I am not proud of the state of the code, but I'll clean it up little by little. The debugger (as it is) is entered on unhandled conditions, and handler-case can be used to handle them.

We are now up to 5 minutes of bootstrapping time, and there are noticeable delays the first time forms are typed in the REPL. I think it has to do with generic functions needing to have their discriminating functions created. But it does come back eventually, and further similar interactions are much faster.

I don't want normal SICL code to depend on the CLIM-based backtrace inspector, so I set that up manually after boot. That way, if I end up in the "debugger", I can type :BT and start the backtrace inspector.

I don't think the functionality of the "debugger" is important right now. It should be entered only if something goes wrong, and then that problem should be fixed. More important is the signaling, the handlers, and the restarts.

So I guess next on my list is the adaptation of the Mezzano stream hierarchy to SICL. It should be straightforward, at least if we ignore threads for the time being.

About I/O, I think it would be possible to use Gray streams everywhere. That way, during bootstrapping, there would be only a few methods that invoke host functions. Everything else can be SICL code.

It is still a bit unclear to me what I/O functions ultimately call the character I/O functions. There seems to be quite a lot of back and forth between PRINT-OBJECT, FORMAT, PRINT, PRINC, etc. I guess that's a decision to make.
