  I don't recall the name, and it was about five or six years ago. Handled by tying $_, if I recall.

    Underscore.pm (named so it could be invoked with no Underscore) is a demonstration of tieing scalars in chapter 14 of Programming Perl (3ed).

    Doesn't seem to have made it to CPAN yet tho' :)

  Style is just another word for taste,
  and there's no accounting for it.

    I think it would be useful in a lot of areas, particularly where you have a company coding standard.

    I have worked to coding standards a few times and have never really had any complaints apart from the shocking hoops required to implement anything useful in asp/vbscript.

  That good Perl 6 style will almost certainly involve using $_ in way more places...

  given $foo {
     .bar;
     .baz;
     .quux;
  }

  Admittedly, the $_ is invisible in most such examples, but that doesn't mean it isn't there.

  You're comparing use of $_ with use of map() and grep() in void context? To me, writing Perl without $_ is like writing English without pronouns. It's hardly a mark of good style.

    I mean, often I see $_ used and modified 5 times in a dozen lines, this is a pig when a program has evolved over time - named variables are usually preferably 9 times out of 10.
