Re^3: Do not understand code

[Eily]

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.

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.

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.
