@_discord_239772388747640841:t2bot.iokrftdnr As Julia explains, and the comments on the Reddit post also explained, there is previous precedent in mathematics for using * for concatenation. 18:03:27
@ngn:matrix.orgngni dont recall ever encountering * as concatenation (but im not a pro mathematician). ive seen || though, notably in cryptography.18:11:02
@_discord_624974820840308737:t2bot.iocoltim overloads I am familiar with: good. overloads I am not familiar with: bad 18:11:09
@_discord_194214927093858304:t2bot.iostackofbears Is * in Julia the monoid operation in general, or is it just overloaded to concatenation for strings? 18:17:56
@_discord_194214927093858304:t2bot.iostackofbears (or the free monoid op where applicable) 18:21:56
@_discord_117836943043198982:t2bot.iodevin.jl it's overloaded with many things 18:21:57
@_discord_117836943043198982:t2bot.iodevin.jl it's number multiplication, matrix multiply, and string cat 18:22:16
@ngn:matrix.orgngnall the operations usually denoted with juxtaposition - no operator at all :)18:23:47

The free product of groups can be seen as a kind of concatenation. It's the only thing that comes to mind, and I had to search a bit because I had only a fuzzy memory of the name. Except for use in language theory as mentioned in the reddit thread, which I suppose counts as mathematics too.
18:37:28
@ngn:matrix.orgngnhm, in language theory i'd assume a * is kleene's star (like in regex)18:39:54
@ngn:matrix.orgngn * hm, in language theory i'd assume a * is kleene's star (like in regex - zero or more occurrences) 18:40:27
@anaseto:matrix.organasetoYeah, I have some vague memory of seing it with another meaning in a book, but I kind of forgot about it, I may be wrong.18:43:16
@_discord_194214927093858304:t2bot.iostackofbears icon is one language that does use || for string concat 18:56:39
@_discord_194214927093858304:t2bot.iostackofbears I swear there are more, but I don't remember who... 18:57:02
@ngn:matrix.orgngn stackofbears: sql? 19:01:07
@_discord_194214927093858304:t2bot.iostackofbears Oh, true! 19:03:02

Oh, true!
Rexx also uses that
23:25:55
@_discord_870115701279584326:t2bot.iodiscodoug I guess spammers don’t run stats to see if they get any bites… 23:28:33
@_discord_194214927093858304:t2bot.iostackofbears I don't think I'd ever heard of Rexx 23:29:48

@loke:dhsdevelopments.comloke stackofbears: it's the standard scripting language on zos and amigaos. And available on many other systems. 02:53:27
@loke:dhsdevelopments.comlokeOh, I think it was used back in the os2 days as well.02:53:43
@_discord_1002703080321728512:t2bot.iotonyc1 Vm/360, cms, there was a version of rexx for pcdos and early windiws 04:16:56
@loke:dhsdevelopments.comlokeYou can run it on the public domain version of MVS too. https://github.com/mvslovers/brexx37005:10:38
