i.e. the difference between `d` and `$` is a single bit. If your cable happened to glitch during that first `1` bit, you would get a `$` instead of the `d` you should have.
The thing is that doesn't happen anymore. Or at least when it does happen it gets caught and retransmitted.
Which means that some of the first people to say it might not have been making a value judgement, but a statement of fact. (I doubt there was very many in that camp.)
Note that I say that as a person who's second favorite language is Perl. (First favorite is Raku, formally known as Perl6.)
It is too bad that most of coolest features have come to Perl after I switched to Raku.
