| 2025-01-16 14:29:32 +0100 | <kuribas> | If it's not lazy, can it be bottom? |
| 2025-01-16 14:27:52 +0100 | <__monty__> | Except for bottom, yes. |
| 2025-01-16 14:27:38 +0100 | <kuribas> | An uninhabited newtype? |
| 2025-01-16 14:27:14 +0100 | <kuribas> | What does that even mean? |
| 2025-01-16 14:26:59 +0100 | <dminuoso> | But cute trick, did not know you could do that. |
| 2025-01-16 14:26:41 +0100 | <dminuoso> | Guess that works too. |

| 2025-01-16 14:26:12 +0100 | <dminuoso> | Oh, right. Thanks |
| 2025-01-16 14:26:01 +0100 | <__monty__> | (inhabited) |
| 2025-01-16 14:24:50 +0100 | <dminuoso> | Now it would be interesting if we could conjure `newtype Bar` equivalently |
| 2025-01-16 14:24:31 +0100 | <dminuoso> | Here you have a type `Foo` inhabitated only by bottom. |

| 2025-01-16 14:24:22 +0100 | <dminuoso> | % data Foo |
| 2025-01-16 14:24:19 +0100 | <dminuoso> | And if "inhabitated by bottom" only came to mind |
| 2025-01-16 14:23:41 +0100 | <dminuoso> | Since even `Type` is inhabitated (by bottom), you cannot even differentiate in terms of "is it habitated" |
| 2025-01-16 14:23:05 +0100 | <dminuoso> | That's really the point of it. |
| 2025-01-16 14:23:02 +0100 | <dminuoso> | Well, the distinction is lost with TypeInType. |
| 2025-01-16 14:22:44 +0100 | <kuribas> | I suppose. '*' or 'Type' is the "kind" Type, while other kinds are also types, but not the "kind" type.. |

| 2025-01-16 14:22:38 +0100 | <dminuoso> | One particular note here: |
| 2025-01-16 14:22:01 +0100 | <dminuoso> | kuribas: Does that answer your question? |

| 2025-01-16 14:20:13 +0100 | <dminuoso> | * and Int are *distinct* types. |
| 2025-01-16 14:20:07 +0100 | <dminuoso> | What do you mean by distinction? |
| 2025-01-16 14:19:49 +0100 | <kuribas> | Then there is no distinction between types '*' and types with other kinds, even though '*' is named 'Type'? |
| 2025-01-16 14:19:07 +0100 | <kuribas> | right. |
| 2025-01-16 14:18:20 +0100 | <dminuoso> | Types of * are inhabitable, but not necessarily habitated. |
| 2025-01-16 14:18:10 +0100 | <dminuoso> | kuribas: Types of type * -> * are uninhabitable. |

| 2025-01-16 14:17:49 +0100 | <kuribas> | No, "Maybe" is not inhabited. |
| 2025-01-16 14:17:34 +0100 | <kuribas> | So there is a difference betwee "Types" and "Type"? |
| 2025-01-16 14:17:32 +0100 | <dminuoso> | In fact, inhabitation and *inhabitability* are qualities of all types. |
