Re^6: perldoc -lf anomaly (%

Follow up:

I just noticed that while @ENV is reserved special, @a is not. Compare %ENV and $a ...

Has this always been the case?

I kind of remember @a being "weird" too.

$ perl -e'use strict;@1=(666)'
$ perl -e'use strict;@STDOUT=(666)'
$ perl -e'use strict;@ENV=(666)'


#but

$ perl -e'use strict;@a=(42)'                   Global symbol "@a" req
+uires explicit package name (did you forget to declare "my @a"?) at -
+e line 1.


$ perl -e'print $]'

I think that's because `$a` and `$b` are package variables, not globals. Same with `@F` under `-a`. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

Hmm yes, $a and $b live - if needed - in the current package and not `main::` `$ perl -E'package tst; sort{$a le $b} 1..100; say exists $tst::{a}; us +e strict; say $a;' 1` [download] Cheers Rolf _{(addicted to the Perl Programming Language :) see Wikisyntax for the Monastery}	[reply] [d/l] [select]
