I had to laugh and just wanted to ask what vidoes you are watching... ;-)

I have to cite from Monty Pythonís Life of Brian:

Are there any women(*) here today?

    Actually our local perlmongers group is "racially mixed" and we like comparing and learning from different approaches.

    I raised a discussion about how easy the counting idioms are implemeted in Perl because undef ++ == 1 and autovivification and was wondering how JS, Ruby and Python and so on are trying to solve this.

    (Our Haskell guy couldn't stop complaining how dirty Perl's behavior is)

    Now try this in these languages

    $count{$_}++ for @names


    DB<135> @name=qw/rachel raymond matthew roger betty melissa judith c +harlie/ DB<136> push @{ $group{length $_} } , $_ for @name DB<137> \%group => { 5 => ["roger", "betty"], 6 => ["rachel", "judith"], 7 => ["raymond", "matthew", "melissa", "charlie"], }

    This video was mailed to me with the remark "this is clean idiomatic Python" and the speaker talks for minutes about strategies to count and group.

    There is indeed MOOOOOORE than one way to do it in Python where Perl has one simply way.


    We are quite fast in criticizing the downsides of some Perl features, it's worth showing where Perl profits from those features.

    "Only an idiot learns from his errors, the smart guy learns from other's errors"
    (attributed to Otto von Bismarck)

    And not everything I learned in this video was a bad idea!

      Hi Rolf,

      I do have my own Python journey behind me. There are many things which are not bad. Be sure, I'm not a Perl fanatic. :-)
