• record struct syntax

Really happy about ReadOnlySpan<char>.

Coming back to readonly structs, what's the proposed syntax for making a readonly record struct? public readonly record struct Point3D(float X, float Y, float Z);?

[333fred]

Yep. We also talked about variants where you could put readonly on the individual parameters if you don't want the whole thing to be immutable.

[HaloFour]

Sounds like that dovetails with readonly parameters in general.

I would assume that as, in the agreed version, record would be a modifier of struct, then record and readonly could co-exist, so it makes sense that readonly record struct would be the way.
