Schedule ASAP
Schedule when convenient
- Discussion of refreshing language spec (Neal)
- Allowing pattern-based
foreach
andawait foreach
to bind to an extensionGetEnumerator
/GetAsyncEnumerator
andMoveNext
/MoveNextAsync
(Julien/Chris) - Making a
CancellationToken
available in async-iterator method bodies; possibly reserving a keyword (Julien/Stephen) - Syntax of positional records/primary constructors (Andy)
- Nullable sidecar files (Immo)
- Nullable Reference Types: Open LDM Issues https://github.com/dotnet/csharplang/issues/2201

Default Interface Methods
See also https://github.com/dotnet/csharplang/issues/406
- Reabstraction (open)
- explicit interface abstract overrides in classes (open)
Pattern-Matching
See also https://github.com/dotnet/csharplang/issues/2095
-
Propose to change precedence of switch expression to primary (open)
The switch expression is currently at relational precedence. I propose to change it to primary precedence. See #2331 for details.
-
Reserve
and
andor
in patterns (open)In anticipation of possibly permitting
and
andor
as pattern combinators in the future, we should forbid (or at least warn) when these identifiers are used as the designator in a declaration or recursive pattern. Otherwise it would be a breaking change. -
To where do null inferences flow from a pattern in a
switch
? (open)- To the entry of the switch and all previous cases
- To that branch of the switch only
- To all code that follows the test in logical order
Nullable Reference Types
-
What is the nullability of a dynamic value? Oblivious? See also https://github.com/dotnet/roslyn/issues/29893
-
When we compute an annotation in the walker (e.g. type inference), do we use the context? See also https://github.com/dotnet/roslyn/issues/33639
-
Inferred nullable state from a finally block (open) See also https://github.com/dotnet/roslyn/issues/34018
