in thread Moose and caller() for current method

Actually have read the draft. A few examples:

  1. Whatever happened to (from "Programming Perl" third edition: section 2.5):
    One of the design principles of Perl is that different things should look different. Contrast this with languages that try to force different things to look the same, to the detriment of readability.

    How does that sit with your take on lexical file handles?

  2. "You can disambiguate this with the postfix package separator (::), but that's rare and admittedly ugly:"

    What is "ugly" about two colons?

    That is nothing but capricious subjectivity. It has no place in a teaching document.

  3. Indirect objects.

    Re-read your stance on indirect object notation. Consider the reason sited for not using it ("rare").

    Consider also the suggestion: "Alternately, consider loading the core IO::Handle module which allows you to perform IO operations by calling methods on filehandle objects".

    And we're back to making everything look the same. Pure dogma!

I could go on (and on), but there would be little point. You've lost sight of what makes Perl so productive. Of what makes Perl, Perl.

(BTW: Why is it that your denials of previous accepted wisdom is legitimate; but my expression, of my reservations of your opinions: "libellous"?)

    How does that sit with your take on lexical file handles?

    All things being equal, the principle of distinction is useful.

    All things are not equal in this case, especially considering issues of global variables and the complexity of localization versus automatic scope destruction and RAII. What should they look like, and what leads you to believe that the addition of lexical filehandles to Perl 5.6 violated the principle of distinction?

    What is "ugly" about two colons?

    The asymmetry of Package::Name:: and its virtual unuse.

    And we're back to making everything look the same.

    Do yourself the favor of reading the rest of the chapter, especially the explanation of why indirect object notation is unreliable.

    You've lost sight of what makes Perl so productive. Of what makes Perl, Perl.

    I find it difficult to believe that Perl's productivity comes from the wanton use of global variables and syntactic constructs with parsing ambiguity.

    ... my expression, of my reservations of your opinions: "libellous"?

    Easy! If you were to write "I think your advice is silly," that's obviously your opinion. If, instead, you write "Your intent is merely to make everyone write code your capricious way for no obvious reason," you've produced libel. (Update: Note the use of the subjunctive mood in this paragraph.)

    You may have the last word in this thread, as usual.

      That's very magnanimous of you to assume the prerogative and then grant it.

      As you both asked me a question; and made several scurrilous assertions, I will respond. Whether it is the last response, is your prerogative!

      you write "Your intent is merely to make everyone write code your capricious way for no obvious reason,"

      Since I didn't write that, nor anything remotely akin to it. Who's libelling whom.

      the wanton use of global variables

      Nor that.

      What should they look like, and what leads you to believe that the addition of lexical filehandles to Perl 5.6 violated the principle of distinction?

      Nor that.

      And that is pretty much the problem with the draft, as it is here. The mixture of fact and fiction. Of documented reality, with unfounded justifictions.

      Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
      "Science is about questioning the status quo. Questioning authority".
      In the absence of evidence, opinion is indistinguishable from prejudice.
