@Plergux -- I spotted you checking in yesterday, Long time. How are the academics going?

@UlrikeFischer Ah, I see what's up

@DavidCarlisle, @UlrikeFischer A PR to review :)

@JosephWright I also think the way the unknown-key handler is undefined \AtEndOfPackage is unfortunate. Consider the following use case: I define keys, I like the default error handling during option-processing, but afterwards I want to define a dedicated unknown handler which does something different in if the \fooSetup macro is used. Now I have to also put that code in \AtEndOfPackage because of something non-obvious.

@Skillmon Huh? It's not - it's undefined by \@@_option_end: as soon as we are done

Sunday quack

@PauloCereda Good morning, Mr Duck.

@JosephWright installing here

@PauloCereda Sunday Lunch

ooh

@DavidCarlisle oh no

@JosephWright

\documentclass[10pt,letterpaper,abc]{article}
\usepackage{doc}

\begin{document}
Hello, world.
\end{document}

I get no warning about abc (also should be PL2 I guess)

@DavidCarlisle maybe it works with zzz

@JosephWright oh you're right, guess that got changed somewhen (or my mind tricked me), I remembered it being in \AtEndOfPackage, sorry :)

@JosephWright I can't look now, I'm out (we had a chess match), I will look in the afternoon.

@JosephWright ooh github.com/cereda/sillypage/blob/main/sillypage.ins#L85

Random comment: It seems that the math class inner is more or less redundant in luametatex.

@barbarabeeton ooh Sunday mail :)

(and @DavidCarlisle is not allowed to complain: tex.stackexchange.com/a/173740/52406)

^^ gosh, we are old

@PauloCereda Haha!

@mickep back then I was a serial upvoter :)

@PauloCereda Ducks get older and older these days, it seems. The only still living part of the dinodododuck.

@PauloCereda And now? A serial nonvoter?

@mickep ooh

@mickep a serial whatever. :)

@PauloCereda serialooher and serialquacker.

@mickep :)

@mickep good riddance

@JosephWright regarding github.com/latex3/latex2e/pull/865#pullrequestreview-1011550954 I think I got the correct rule set right in the documentation of expkv-opt, so you can use it as a reference implementation :P

@DavidCarlisle Thanks. (The only traces left were \ldots, \cdots, ... (a bit strange also, when one uses the unicode slots for them))

@Skillmon I think I had the rules right before the brace stuff .. but I will check what you have :)

@JosephWright Well, if you happen to find a mistake on my end, please let me know :P
