Are Restricted/Locked Hashes a Failed Experiment?

    demerphq kicked off a discussion on of the hash APIs that Perl (and perl) provides. The discussion also has a parallel strand on

    In my interpretation, the discussion moved on from removing restricted and locked hashes towards realizing that restricted and/or locked hashes can get a different hash implementation in the backend than plain hashes and maybe even plain hashes can get different implementations. This makes me somewhat happy because I really like using locked hashes for DBI query results and don't really care for the (potential) performance overhead.

    Other people see a benefit in removing the performance overhead incurred by supporting restricted hashes, which I don't know about. But as these people know more about the internals, I'm inclined to trust them on their judgement as well.

    Allowing different implementations of hashes opens up the interesting question of if or how a hash can move from one implementation to another, and personally I expect that only to happen for explicit assignments:

    use feature 'superfast_hashes'; my %hash_with_implementation_A = ( foo => 'bar' ); no feature 'superfast_hashes'; my %hash_with_implementation_B = %hash_with_implementation_A;

    If you have an opinion either way on the features of locked / restricted hashes, consider participating in the discussion either on or

    Because of the hard work of Kenichi Ishigaki (ISHIGAKI on CPAN, charsbar on IRC), Text::CSV is back in sync with Text::CSV_XS again. That must have been an awful lot of work. THANK YOU!

    Enjoy, Have FUN! H.Merijn

    Hi. I made a new release of a tiny but fast OO module and marked it as "in alpha state". It's like a Moose, but requires less typing

    Check the syntax here

    Check it out On CPAN

    Need feedback.

    PS: Also it contains a new "Exporter", "Dependency injection", "Promises", "try_catch" for quick and safe application development

    With David's permission and blessing, I've merged the numerous updates and features I wrote into my berrybrew into his.

    If you want or need his previous version, checkout this commit (6bc28ae).

    I want to thank David for providing this software originally, and being very polite and easy to communicate with. I do not use Windows as a normal platform, but whilst writing Test::BrewBuild, kind of needed it, and the only Windows perlbrew that was available.

    Thanks David!
