I guess there is another possibility, namely that ENSURE-GENERIC-FUNCTION checks whether the generic function exists, but that would be silly since that is what the generic dispatch of ENSURE-GENERIC-FUNCTION-USING-CLASS does.

beach: where does the MOP entry say EGFUC passes :method-combination through without supplying a default?

In older systems with high-end pointer tags, it was not uncommon for fixnums to have all-zeros for positive fixnums and all-ones for negative fixnums

OK, if I trace ENSURE-GENERIC-FUNCTION-USING-CLASS on SBCL and then type a DEFMETHOD form without a preceding DEFGENERIC form, no keyword arguments are given.

So if the :METHOD-COMBINATION keyword argument is not supplied to ENSURE-GENERIC-FUNCTION-USING-CLASS, the method specialized to NULL must supply it. But it could be supplied, so that has to be taken into account.

I am making progress on DEFMETHOD without preceding DEFGENERIC. It was complicated because I hadn't written the code for computing a congruent generic-function lambda list from a method lambda list.

Also, in ADD-METHOD, I need to check whether the LAMBDA-LIST slot in the generic function is bound, and during bootstrapping none of the machinery for SLOT-BOUNDP etc. works. So I define SLOT-BOUNDP as (CONSTANTLY T) during bootstrapping, because this is the only place it is called, and the slot will always be bound.

Because heisig had the idea of putting all the DEFGENERIC for the sequence functions in one file. So if I want to check whether I can load a sequence function using my special macro, I would have to load them all in one go if I had to execute the DEFGENERIC first.

Time to call it a day. I'll hang around until my (admittedly small) family announces that dinner is served, which will be in the next 20 minutes or less.

My (admittedly small) family just announced that dinner is served. I'll be back tomorrow morning as usual.

ac-slime does not play well with sicl repl, if autocomplete kicks in (ie popup) it freezes emacs. Is there anything I can do about it or should I just disable autocomplete in the repl?

scymtym: wow, what a difference from auto-complete! For one it actually looks great and keys are dont have different behaviour between repl and lisp file buffers!
