I'm afraid that link has disappeared. I'll try to look it up in archive.org.

It does not exist. So unless @FCO remembers what this is about, probably closing it.

I don’t :(

Maybe replicate the example? Should be as easy as

class Proxier is Proxy {}; say Proxier.new.raku

Although in this case subclassing work; .new does not. Closing it, unless someone finds another interpretation for the OP.
