in thread Perl 5 Optimizing Compiler, Part 9: RPerl.org & The Low-Magic Perl Commandments

Obviously, obviously ...

The essential point of my thread was of course not a quibbling as to the actual byte-size of “the language-compiler/runtime component,” but rather to emphasize that “the language-compiler/runtime component,” ... nor any low-level details of its implementation ... “is not the real point here.”   Every bit of that “plumbing” is just A Means To An End, and in any case it is a minuscule portion of the total body of source-code that is of professional interest to me.   In the long run, I don’t really care if, say, DBI “runs x% faster.”   But I do rather-profoundly care that it continues to pass 100% of its thousands of tests.

    sundialsvc4,

    Simply put, nothing in RPerl will break your code. It may only give you marginal benefit if you use all high-magic code, but backward compatibility is our goal.

      en re; (low|high)magick,majick,...
      How 'bout "black-magick" v "white-magick"?
      I'll leave it up to the viewers, to decide to which Perl, one, or the other should be ascribed/applied. :)

      --Chris

      #!/usr/bin/perl -Tw
      use Perl::Always or die;
      my $perl_version = (5.12.5);
      print $perl_version;
        Howdy taint,

        I like your idea! I guess in my mind all the things forbidden in The Low-Magic Perl Commandments are "grey magic" (neutral) at best and "black magic" (bad) at worst.

        Although the forthcoming "use magic;" and "no magic;" pragmas are seemingly binary in nature, in reality there is still a small amount of magic kept in RPerl, thus the term "Low-Magic Perl". I consider all the magic remaining to be "white magic" (good), such as memory management, garbage collection, hash data types, Perl's list of builtins, and other DWIM-like features. So the "Low-Magic" of "Low-Magic Perl" is "white magic".

        :-)

        DISCLAIMER: Nothing in this message should be considered canon, see RPerl.org for all things official.

        Perling,
        ~ Will the Chill
