2025-02-24 23:23:20 +0100 <EvanR> parenthesized by braces, braced by brackets, and bracketed by parentheses
2025-02-24 23:22:54 +0100 <monochrom> I guess Coq's is like "Type @{...}" so it is parenthesized, by curry braces.
2025-02-24 23:19:47 +0100 <monochrom> But you would need the parens in Lean. :)
2025-02-24 23:19:43 +0100 <ncf> average coq documentation experience
2025-02-24 23:19:38 +0100 <ncf> there seems to be syntax for specifying levels explicitly but i can't tell how it works https://coq.inria.fr/doc/V8.18.0/refman/language/core/sorts.html#sorts

2025-02-24 23:18:01 +0100 <monochrom> Coq does not allow you to write "Type n" or "Type (n+1)". It only lets you write "Type" and it infers the level.
2025-02-24 23:17:28 +0100 <EvanR> do you need the parens in Coq
2025-02-24 23:16:59 +0100 <EvanR> lol
2025-02-24 23:16:56 +0100 <EvanR> now I won't know
2025-02-24 23:16:41 +0100 <monochrom> "Type n : Type (n+1)"
2025-02-24 23:16:34 +0100 <monochrom> :(
2025-02-24 23:15:58 +0100 <EvanR> is the precedence of Type _ really less than addition there
2025-02-24 23:14:52 +0100 <monochrom> Bad habit from Coq I guess. You just write "Type" and it means "Type n" where n is inferred from context. So you write "Type : Type" and it is nothing paradoxical, it is inferred to be "Type n : Type n+1"
2025-02-24 23:14:24 +0100 <tomsmeding> but if the answer to that question is "it's in U", then you might as well just destroy all Un with n >= 1, because you'll never need them, and then U = U0 because there's only one universe

2025-02-24 23:13:36 +0100 <tomsmeding> for example U0
2025-02-24 23:13:31 +0100 <EvanR> shoot
2025-02-24 23:13:25 +0100 <tomsmeding> I meant U for any Un
2025-02-24 23:13:20 +0100 <tomsmeding> sorry
