    the then-present value of a variable, $_, which the Perl language does not even name.

    I was curious if this was true, so checked English. Interestingly, to me at least, it does have a name but I admit its name is barely any better than not having one at all and probably why I didn't already know the answer without needing to look–

    perl -MEnglish -le '$_ = "moo"; print $ARG' moo

      I'm worried that this talk of translating $_ into English is neglecting the all-important needs of the Perl poet, specifically the crucial Perl haiku (5-7-5) syllable count, where traditionally $_ is pronounced as "it" and @_ as "them", as in chipmunk's winning TPC 4 poem (where his subroutine summer is both a "sum-er" and a season):

      sub summer { my $sum; $sum += $_ for @_; $sum } print summer (split);
      and is pronounced (5-7-5) like so:

      sub sum-mer my sum
      sum plus equ-als "it" for "them"
      sum print sum-mer split

        the crucial Perl haiku (5-7-5) syllable count

        Far from crucial, the 5-7-5 syllable count is unnecessary. The idea that it's central to the definition of haiku is bogus. Pure myth.

        I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.

      Actually I would expect $ARGV for $_ to mostly be a side effect of @ARGV for @_. This also works for other punctuation variables and their english versions

      perl -MEnglish -E "@; = q<Hi>; say @SUBSEP" Hi
      It's not a name that perl parses, but I'd expect pretty much everyone here to understand what "the default variable" refers too.

        > to understand what "the default variable" refers too.

        We could consider adding $DEF or $DEFAULT for $_ to Perl.

        > @; = q<Hi>; say @SUBSEP

        I suppose these are just glob aliases, that's why they work for all types associated to a symbol.

      It takes too much energy correcting all inaccuracies in sundial posts in replies. *

      If it was possible to edit foreign posts (like in SO), sundials would be normally full of strikes and red comments.

    This statement is about to perform an irrevocable act: it is going to delete a file.
    There are three posibilities: 1) the file is not terribly important, 2) there is a backup of the file, and c) you are an idiot. But I'm still waiting to hear how you, in your infinite wisdom, think it should have been written. This should be good.
      "c) you are an idiot"
