  • My gosh ... I've got 30 year old perl code that uses shelling of that time, and still runs.


    This ... isn't a win.


    That, and I really miss the ease of


    if ($var =~ /regex/) {


    }


    blocks. No real equivalent in Py. Lots more boilerplate around using regex. /sigh

  • Code works perfectly in Py3.9. Breaks in Py3.6. Looks like subprocess semantics are different between the two.


    Just ... wow.


    I could say bad things about the language. But the point of using these scripting languages is speed of development without much defensive coding.
