So does `my $_;` and `my $var;`. Is there a case where `my` doesn't create a new variable?	[reply] [d/l] [select]

my $_ is new with 5.10.0, and switches anything in the scope that by default is using the global $_ to using the lexical $_ instead. my @ARGV has no such magic. `readline` or `eof` will continue to default to using the global @ARGV, even though there's a lexical @ARGV in scope. This is the reason for a warning. -- Online Fortune Cookie Search Office Space merchandise	[reply] [d/l] [select]

My point is that I am looking for cases of Perl code that compile under use strict. Don't generate warnings under use warnings but don't do the expected by a beginner. After being told to use strict and declare everything with my, a beginner will go out and do just that. Declare everything with my: `my (@ARGV, $a, $b, $_, $AUTOLOAD);` [download] you could give them a list of special cases but IMHO it is a waste of brain cycles - at that point in the learning curve. Probably they will not learn them and the whole thing will just confuse them. My plan is to provide a tool that can find such cases and warn about them.	[reply] [d/l]
