I second the notion of a separate role, like Str vs. Stringy. However, the idea here is that a Blob is an immutable Buf. AFAICT, the roles are agnostic concerning mutability: you have Positional, which applies to both Arrays and Lists (IIRC). So you'd have one of Blobby or Buffy, but not both. Or perhaps you'd have another name for it that captures the essentials that Blobs abd Bufs share, without "privileging" one over the other. Or not. -- Jonathan "Dataweaver" Lang
