Agenda

Nullable open issues:

1. Remaining questions on suppression operator (and possibly cast)
2. Does a dereference update the null-state?
3. Null contract attributes
4. Expanding the feature
5. Is T? where T : class? allowed or meaningful?
6. Confirm that oblivious should be ephemeral
7. Unconstrained T in List<T> then FirstOrDefault(). What attribute to annotate FirstOrDefault?

[orthoxerox]

Is it possible for you to share the list of null contract attributes there?

[agocke]

@jcouv I believe you had the full list. Could you link that?

[jcouv]

The list of attributes is not finalized yet. The issue tracking this has a good number of ideas: dotnet/roslyn#26761

@agocke shouldn't the link be LDM-2018-08-20.md, rather than 07-20

[agocke]

Yup, typo. I just updated this, but the content is the same, so I'll keep the current link.
