07:48 <Nistur> mornin'

07:51 <beneroth> Good morning

07:51 <beneroth> Nistur, you appear to have multiple mornings? On which planet? :D

07:51 <beneroth> How are things?

07:51 <Nistur> time is an illusion :P

08:01 <beneroth> I'm not sure. It is certainly a delusion, but I guess the limited supply of it is too damn real.

08:02 <beneroth> <advertisement> Thus I program PicoLisp - live is to short for programming languages where I have to type more than to think.

08:25 <razzy> hi all

08:31 <Regenaxer> Hi razzy, beneroth, Nistur

08:31 <beneroth> Hi razzy, Regenaxer :)

08:37 <Nistur> o7

08:40 <beneroth> Regenaxer, I have a list which contains an element 'foo. I like to get the head = the list of elements in the list previous to 'foo (so kinda the opposite of 'member function).

08:41 <beneroth> Regenaxer, (index) + (head) or (make) and (find) ?

08:41 <beneroth> list are usually rather short (maybe dozens of elements), so I guess (index) + (head) might be faster even when it involves multiple iterations over the list ?

08:42 <Nistur> beneroth: "Time is an illusion" seems to be a quote attributed to Albert Einstein. When people question my use of UGT, I tend to use that, which makes me seem clever, when in my head I'm really thinking of the Hitchhiker's Guide to the Galaxy, which continues with "and lunchtime doubly so"... and follows the line "3 pints [of beer]! At lunchtime?"

08:42 <beneroth> (lists can happen to be long, with hundreds or thousands of elements)

08:42 <Regenaxer> hmm

08:42 <beneroth> Nistur, nice one!

08:43 <beneroth> Regenaxer, I could use (find), (make) and (==)

08:44 <Regenaxer> Yeah, index + head involves less fun calls

08:44 <Regenaxer> the latter calls a function for each element

08:45 <Regenaxer> So 'head' is faster I think

08:48 <Regenaxer> also simpler than 'link'ing inside 'find'

08:49 <beneroth> T

08:49 <beneroth> ok I do that, thanks!

08:49 <Regenaxer> :)

09:19 <beneroth> Regenaxer, I developed a taste for ((if Flg ...) ...) function calls :))

09:19 <beneroth> very handy in some specific cases

09:19 <Regenaxer> yeah

09:20 <beneroth> very picolisp-specific language feature

09:20 <Regenaxer> saves duplicate code

09:20 <beneroth> T

09:21 <beneroth> Regenaxer, I guess (chain (copy Lst)) is better than (mapc link List) ?

09:22 <Regenaxer> yes, again cause of fun overheads

09:23 <beneroth> I keep it in mind :)

09:24 <beneroth> Thanks!
