    Folks acting like Python is the only language without semicolons. 😏

    I got tripped up so many time in the last 3 weeks using PHP after years in ML family languages. I am already newlining & it’d be poor style to put more than one statement on a line so what is the point of these semicolons?

      In some languages
      a newline does not
      necessarily indicate
      the end of a statement.

      In others, sometimes it could, but would leave things ambiguous
      as to whether the statement was ended or not.

      And so, punctuation is necessary.

        But newlines + indentation are supported by a lot of languages & when it is, it’s easier to read since the prevailing convention is already to newline, then in indent. When you follow the usual coding styles or autoformatted & removed the semicolons, you’ve gained nothing for readability & added noise. I much prefer the languages that take this convention & bake it in so you don’t have to have that that visual noise—and in these languages, I never felt the parsing rules were ambiguous.

      Unlike Python, most languages do not endorse a specific concept of style. You’re free to dabble in all the bad style choices you like, on the off chance that once in a blue moon they prove to be situationally useful.

        Why haven’t custom parsers become more of a thing? All the compiler or interpreter really needs is a valid parse tree. You could even have some kind of special command or directive to switch styles, if a section would be really ugly otherwise.

        With indentation-based languages the bad coding style we are talking about is putting multiple statements on a line or unindenting a block …& never has that been something I wanted to do. I would rather this aspect be enforced at the language for readability where there is still room in all other aspects to try out other styles.

        The best languages about really embracing punctuation as you would in English is Prolog & Erlang with their periods, semicolons, & commas.
