Proposal: record structs

[jcouv]

• Proposal added: https://github.com/dotnet/csharplang/blob/main/proposals/csharp-10.0/record-structs.md
• Discussed in LDM
• Decision in LDM
• Finalized: Done
• Spec'ed

Allow value type records with record struct.

Secondarily, we would also allow record class (with same meaning as record) and allow explicit declarations of positional members using different member kinds (get/set property, or field).

Just remove the (.) at the end of the link.

The link is also /edit/ rather than /blob/
