With Ada, it's not defined whether copying or referencing occurs with in out parameters, sans some special cases such as limited objects.

The fact that SBCL no longer complains when there is a DEFMETHOD but no associated DEFGENERIC does not suit me at all. My worsening dyslexia results in numerous spelling errors that are not caught.

ACTION wonders if a general utility to check all symbols for a close Levenshtein distance would be useful

Here I have a tool to check for "duplicate" symbols, ie. symbols with the same name interned in different packages. https://github.com/informatimago/lisp/blob/master/tools/symbol.lisp#L133

Just realised how good the logs are for this channel. Thank you to the kind people who maintain them!

int = 5; void a(int &n) { n = 2; } std::cout<<i; // 5 a(i); std::cout<<i; // 2

i think you've been told this before, but if you insist on asking sbcl specific questions instead of using cffi, ask #sbcl. they'll probably tell you to use cffi and you should probably listen
15:37:09
Bike
also, with fixnums, like in your attempt at a C++ analogy, it definitely won't work since they're just immediate and do not have addresses
15:38:30

@Bike; OK. Then how change value variable inside function that will be changed outside function?
15:39:23
Bike
You cannot pass a reference like you can in C++. You can only pass values as arguments.
15:39:51
Bike
You can do things like (let ((x 2)) (print x) (funcall (lambda () (setf x 5))) (print x)), which will print 2 then 5.
15:40:42
Bike
Lisp just does not have references. You can pass objects and modify objects: (let ((x (cons 2))) (print (car x)) (funcall (lambda (c) (setf (car c) 5)) x) (print (car x)))
15:41:16
Bike
But lisp has an entirely different model of things from C. Variables do not "have addresses".
15:42:03
asdf_asdf_asdf
@Bike; Did it mean, that every time variables has different/other/another addresses?
15:45:18
Bike
If you write something like (let ((x 2)) ...) for example, there's nothing stopping the compiler from simply storing 2 in a register, or perhaps using a different register for the same variable in different places, or maybe it will put it on the stack, or maybe it will eliminate the variable entirely and the value won't even exist in a register.
15:47:56
asdf_asdf_asdf
OK. So, why in SBCL are instruction such as get-lisp-obj-address, int-sap, etc?
