2025-01-17 23:59:00 +0100 <EvanR> constructible or countable?
2025-01-17 23:58:40 +0100 <haskellbridge> <thirdofmay18081814goya> a countable universe
2025-01-17 23:58:27 +0100 <haskellbridge> <thirdofmay18081814goya> EvanR: oh ok well, the statement is that terms/values of a polymorphic function type are indexable by the indexability of a constructible universe

2025-01-17 23:57:03 +0100 <c_wraith> Also, there are only countably many Haskell values for practical reasons like programs being countable and the total amount of input a program can receive being countable.

2025-01-17 23:54:24 +0100 <EvanR> when you said "this one" there was nothing posted before you then said "this is not necessarily the case" maybe the bridge lost it
2025-01-17 23:54:14 +0100 <c_wraith> It's secretly useful!
2025-01-17 23:54:09 +0100 <c_wraith> have fun with that one.

2025-01-17 23:53:43 +0100 <EvanR> how do you traverse a function value with or without finite time
2025-01-17 23:53:34 +0100 <haskellbridge> <thirdofmay18081814goya> this is not necessarily the case for e.g. values of coinductive types

2025-01-17 23:53:28 +0100 <EvanR> "traversability of a value" is a bit weird

2025-01-17 23:53:16 +0100 <haskellbridge> <thirdofmay18081814goya> this one
2025-01-17 23:52:50 +0100 <haskellbridge> <thirdofmay18081814goya> so there might be infinitely possible values, but as long as any given value is traversable in finite time, it is a datatype
2025-01-17 23:52:49 +0100 <EvanR> what statement
2025-01-17 23:52:30 +0100 <haskellbridge> <thirdofmay18081814goya> hm right but the statement specifically targets types whose terms are finitely traversable
2025-01-17 23:51:50 +0100 <EvanR> infinite data might have non-countable possible values, for some value of possible
