@PawelGerr I believe that's caused by https://github.com/dotnet/roslyn/pull/58059, which says: > This is technically a breaking change, but the only thing it breaks is invalid code, so I think we should...

@gafter How do type classes let you convert a lambda (including its closure) to a struct?

@CyrusNajmabadi > The normal string-switch works by building a dictionary and switching on that. That likely wouldn't work for ReadOnlySpans. Why not?

@Sour-Codes The recommended way to enable preview features is to do it for the whole assembly by adding `true` to your csproj.

@333fred Since anonymous types can't be exposed publicly, why would that be a problem?

One thing to consider regarding resolution by type: would it make sense to forbid implicit parameters of "primitive" types like `int` and `string`? For a type with well-defined meaning like...
