  • Posted Perl is not a multi-paradigm language to [deleted]

    Perl is a dialecting programming language.

    A dialecticing language is a super-set of a multi-paradigm language. Lisp is another dialecting language.

    Unlike lisp, where everything looks like an s-exp, a Perl dialect will look ridiculously different from Perl.

    Frameworks are like declarative programming systems built over a language. They are not general, and they don't always tell you this, which is _clever marketing_ on their parts.

    I have been burned by _clever marketing_ enough number of times so as to hate them.

    It eliminates method polymorphism.
    Makes it simple for over-riding inherited method, as there is only one method.
    Now that makes Liskov Substituion simpler to implement.

    The field of computation has many many metaphors. Objects is one of them.

    To be honest, I don't really understand object oriented programming. I understand procedural programming aka C.

    Just thinking out aloud, for the sake of clarity.

      great stuff - really happy to see you like qore.

      BTW qore already has in svn now some major new optimizations for integer operations (mostly applied to local variables) and also "pseudo-methods" which are pretty cool - these are class-type methods that can be executed on any value, whereas the "pseudo-class" depends on the value type - for example there are now methods like

      bool ::empty() {}
      *string ::firstKey() {}
      int ::typeCode() {}
      ...

      pseudo-classes are in a (relatively flat) hierarchy - all pseudo-classes inherit from ....

    • mugwump commented on My take on Modern Perl

      Far better than duck typing (at least as implemented in most languages) is what happens using, eg templates in C++. Because C++ is compiling, it will expand out those types in all the functions where they are used - and check that there is a typesafe match with the object type being passed and the method being called.

      "Interfaces" and "Roles" are almost as good, but they still require that the class in question implements the role as passed.

      I did recently see a language where you specified what a role means, and then any class which implements a definition in line with that…

    • Reini Urban commented on My take on Modern Perl

      LeoNerd: You still haven't got it.

      I will provide *optional* ways to cut off generic types.

      The user or library author can decide by themselves that certain data will be typed. And get safety, speed and less size for it. There is no need everything must be generic, there should be a way to enable programmers to restrict their data.
      You leave the type off, and then you can overload or tie or upgrade it to your wish.

      In lisp this optional typing is done with "(the type what)" http://www.cs.cmu.…

    • David Nichols commented on My take on Modern Perl

      Reini, could you please tell me what channels are in this context (the technical idea behind this concept)?

      Qore uses lightweight web service protocols for communication - different from IPC because the 2 communicating parties don't have to be on the same system. One big drawback is that so far I don't have any way of serializing objects over these protocols. The protocols supported so far are XML-RPC, JSON-RPC, and, by far my favorite, proprietary YAML-RPC (because AFAIK there is no real standard for this yet).

      In a single process, threads will typically use Queue objects …
