To me it’s not unlike spending all of a thread about Clojure commenting on Java or Common Lisp without even bothering to mention or contrast to Clojure.
There are connections to both but that doesn’t necessarily make them topical.
I disagree that discussing a previous language by a designer (often in terms that seem to conflate equivalence) is usefully relevant to discussion of a different language by that designer.
Note that I have never said that there is zero utility. I just find it tiresome to encounter comments about Perl syntax as if it is automatically useful or interesting to discussions about Raku.
Which is why I took the time to provide an example of what (I would consider) an actually relevant mention of Perl syntax.
