No dump extensions for ref structs has been derinde for dump
Would it be possible to add extension with signature:
public static ref T Dump(ref this T v) where T:struct
I don't believe this is possible: ref structs can't be used as type arguments.
LINQPad 6.5.x has specific Dump overloads for Span and ReadOnlySpan, which is why you can dump those types.
