(not) Fun with unquote fragments

You’re trying to utilize both behaviors in your macro, which means you’re forced to use bind_quoted: …, because otherwise it’s ambiguous which kind of unquote() should happen. So the following does work just using unquote fragments, having the AST type unquote() disabled be…
