16:15:19 cmack whew. just read planet.lisp and... I am making mistakes everyday

16:30:00 jackdaniel I have a special place in my heart for people who have no doubts about being right; not a soft spot, mind that :)

16:56:09 edgar-rft rule number 6: if you read planet.lisp you are making a mistake

17:07:59 cmack I won't go that far. Even if I disagree, I still enjoy thinking privately about why and still periodically asking myself "am I missing anything?"

18:30:16 cdegroot Also, for my own code, I often (well... usually) explicitly break all the rules. It's a good teacher on _why_ some rules are a good idea :). I like the "essential rule" best.

21:08:25 aeth I would agree on LOOP, but if you need LOOP's collect/append, there's no real way around it

21:09:02 aeth And there are so, so many times where you need to conditionally collect and/or append (even messier to avoid LOOP if you need to conditionally do either one of the two in the same loop)

21:10:42 jackdaniel collect macros are a thing

21:11:03 jackdaniel and can be used orthogonally to iteration

21:20:16 aeth Yes, but LOOP is a standard way to have an arbitrarily complex conditional collect and/or append into one or more lists that's almost certainly going to be one of the most efficient ways to do it in the implementation.

21:21:05 aeth The downsides being that it's annoying to use logic inside of a LOOP and that it's annoying to handle multiple return values inside of a LOOP

22:09:19 decweb If my collection logic is complex I'll often just use `serapeum:with-collector`, perhaps more than one.

22:09:53 decweb The convenience of `LOOP COLLECT` and should be similar efficiency, but more flexibility at the cost of the WITH form.

22:10:45 decweb (and you can use it in the LOOP of course)

22:28:39 aeth I personally don't pull in nontrivial dependencies (except for the ones so common that everyone will include, such as alexandria and uiop; although alexandria is bordering on trivial)

22:29:51 aeth Basically, "Does it have dependencies?" and "Can I read its entire source code?"

22:31:23 aeth For instance, I've read the entire source of float-features and it doesn't depend on anything big.
