@user Turns out I needed to do is None not == None
'cause Python lets things be all woogly

oh yeah
python do be like that
is None is how you check for None
yeah

@RydwolfPrograms Oh, that makes sense, you can override __eq__
Does None == foo work?

is None is the pythonic way to do it though

@RydwolfPrograms Not to mention the fact that people keep using me as a scapegoat for all the mistakes they make

@lyxal fwiw there is a library to add algebraic effects to Scala
Only it's not maintained anymore, afaik (the designers created a whole language: effekt-lang.org)
lyxal
lyxal
01:35
even then, a simple 22 line python generator becomes a nasty looking 69 (nice) line lazylist unfold
which requires a Tuple5
([BigInt, Option[BigInt], Option[BigInt], BigInt, BigInt])
user
user
No I mean, with algebraic effects, you basically get generators
lyxal
lyxal
do algebraic effects add suport for continue and break?
user
user
You can already do that (jankily) with exceptions
scala-lang.org/api/current/scala/util/control/Breaks.html
lyxal

Well that's the bloat part
It makes the 22 liner a 69 liner

Ooh, what's the variant? (and the network?)
Rydwolf Programs
Rydwolf Programs
My friend in comp sci made a game he calls "cursed chess" (a lot of the cursedness was discarded as it actually became playable), which features merging pieces pretty heavily (there are 59 distinct pieces possible as a result, ~50 of which are slightly different combinations of the basic ones)
user

It takes some brain wrapping to understand the merging rules, but once you get them they make sense. Basically, every mergable piece has a "base" piece and possibly others which have been merged into it. So if you move a knight onto a bishop, you'd have a base knight merged with a bishop. Then if you move that onto another piece, you add its base piece (and only its base piece) onto the one that moved
There are special cases for pawns (and a variant of pawns, "flankers"), which turn into various levels of "scouts" (which, at level 3, can eventually move in a 5×5 grid arbitrarily), knights which merge into "smilers" (knights but 2-4 instead of 1-2), and rooks merge into "catapults" (only move side to side, can capture ahead a fair distance without moving to the captured space)

hello people who have used chat for way longer than me. is there a way (setting, script, extension, whatever) to have a count of unread messages next to the names of the chats in the main page, and/or when I open a chat?

Q: How did White lose all their pieces?

Tim SeifertRecently, I have been dabbling in composing a few retrograde chess puzzles. This one, I feel, turned out quite nice: In the game leading to the position below, White somehow lost both their rooks and knights. For each of them, can you determine where they were taken and by which piece? (Bonus po...

Does it also have the counterpart "forget"? In Rust that deletes a reference to something but doesn't clean up the actual thing. Though not sure what that would mean for a file

Erel Segal-HaleviAfter some time of programming in Python, I have learned that many tasks, which previously I performed in several lines, could be solved in a much more succinct way by one-liners, e.g. these ones.

If ] were redefined to test the current cell and conditionally jump back to the beginning of the program, it might possibly be TC. If ] unconditionally jumps back to the beginning of the program, then it's definitely not.
@NewPosts Make it a popularity contest

wait does ] not conditionally jump
or does it always jump back and then [ may conditionally jump back to beyond the ]
I guess there's no difference UNLESS you allow unmatched ] to be valid, lol

Yeah, the usual definition AFAIK is that ] simply jumps back to the corresponding [
