I assume GP posted ironically because the Rust snippet is mostly pretty bland function and method calls, the only weird-ish bits are the postfix "?" (which have become very common[0]) and the block syntax[1], while they're using 3 different sigils in a Perl snippet I'm not even sure makes sense (though it's probably valid because perl) e.g. from what little I've retained of perl (against my will) "@ARG" is an array with the command line arguments, $ARG does not exist, this just passes `undef` repeatedly to `do_something`.
