Collection Expressions Documentation Lists Convertion To Inline Array

[MrKWatkins]

Issue description

The conversions section of the collection expressions docs (https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/collection-expressions#conversions) states that conversions to inline arrays are supported. However this does not seem to be the case; I get CS9174 when I try, and https://github.com/dotnet/roslyn/issues/69236 / https://github.com/dotnet/roslyn/issues/68927 imply that support for conversion to inline arrays didn't make it into C#12. I'm therefore assuming the docs are incorrect?

I hope this will get attention. Working with "InlineArray" without collection expresion is very annoying.
