I think it would be interesting to do a metastudy on metasyntax and how people write things, especially in dependent type theory
I know someone already did one for all the different notations people use for substitution but there's a lot more than just that
I don't know what questions would be interesting to ask though

re: dependent pairs 

I'm adding pairs and I was wondering about this again. I'm glad I wondered about this in the past so I don't have to do it again, but I realize I never really actually stepped through whatever inconsistency proof it was with dependent pairs in prop

I gotta say, though, defining a lot of small rules is a lot more digestible than defining one gigantic frankenrule for case expressions

It's annoying that for every new construct I add to my language, I need to add the type former, the introduction form, the elimination form, and typing rules for all of these

This macro

\WithSuffix\newcommand\Pair*[2]{#1 \mathbin{\times} #3}

Illegal parameter number in definition of \WSF:\Pair the character *.

but you know what? It's right. I just can't read. I used #3 instead of #2
That took a bit to debug

To quote @vdash,

There is so much about equality. I feel like 99% of type theory is about equality

Can you believe I spent a month trying to find a semantically-justified representation of the infinite size only for a simple isInfinite? function to hold more promise than HITs or quotient types ever did

I got nerd sniped and this is what happened

Apparently I can apply for a staff card at my university because I'm an employee and I have an employee number

They're now all divided up into tidy little (too many) folders
idk what the point is but I've done it

I spent the morning organizing my emails

Once I had to say the word "redexes" out loud for whatever reason and I had to stop myself from saying "redices"

If I spent as much time figuring out what I need to install as I did complaining would I have it working by now? Probably not. Guess I should spend some more time complaining to balance it out

One of these days I'll properly figure out how to get my tablet to work on Manjaro
