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);` [download] 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	[reply] [d/l] [select]

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.	[reply]

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` [download] It's not a name that perl parses, but I'd expect pretty much everyone here 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.

I suppose these are just glob aliases, that's why they work for all types associated to a symbol. Yup, as confirmed by reading the code for English. @- and $- have different names though, so only the ARRAY and SCALAR portion of the glob are used in those cases. I was about to say that if you want to have a longer name instead of $_ you can just use a lexical instead (I was thinking of for loops), but I forgot about grep and map where you have to use $_. $CURRENT would work in those cases.

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. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!} *) that's the DOS feature which makes him similar to trolls.	[reply]
