It′s mid-fall which means a new version of C# is coming soon. It′s time to find out what updates will soon appear in the language. Although C#12 has fewer features than previous versions, it still...
they actually have to reference the function by string name.
This is true of a lot of the opt-in language features though, isn’t it? For example, you can just make an .Add method on any IEnumerable type and get collection initializer syntax supported for it, even as an extension method. The same works for Dispose on ref structs I believe, and I remember there being a few other places where this was true (GetAwaiter I think?).
Look how clunky it is to add support on a collection. Take the example here:
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/collection-expressions#collection-builder
It involves adding a new builder class, and they actually have to reference the function by string name.
It’s actually making me even more angry now that I look at it in detail.
