    Perl actually uses my and our to do scope.

    my @foo;

    our $bar;

    This is a great one. I’m definitely using it in class this fall to explain static variables.

      Fun fact: I made this meme to explain my classmates static variables.

    personally I prefer including the file

    prog_constants.h

    int program_state; // Keeps track of stuff

    in all translation units. That way I can easily keep track of what different parts of the program are doing at any time by modifying a single variable.

      int variable => local scope => my int from the perspective of an instance

      static int variable => class scope => our int, for all instances of a class
