Probably was downvoted because it seem to copy-paste/derive-off an LLM output since, even if you say you wrote it yourself, some distinct LLM grammar/style characteristics appear. (Could just be you picked them as habit after use of such tools.) It doesn't appear to in same vein either. The submitted article's descriptions are, for each language, {philosophy} & {specific design examples}. Yours is mainly on {design}.

That said, agree Raku is cool. A big disadvantage though it has (or had?), more than the sigils-everywhere syntax & small ecosystem, is performance. It's slower than pre-JIT Python. Go also natively-compiles to self-contained binaries, which some people appreciate. (And there're those that prefer Go's simplicity and don't want very high expressiveness other than specific features.)

Well - sure - I meant wrote as in "sourced a set of relevant sentences from ChatGPT and then close edited them to convey precisely what I wanted to say" - got me bang to rights there!
